Published: May 2024

Permintaan uang memiliki pengaruh yang signifikan dan berpotensi untuk meningkatkan perekonomian Indonesia. Teori permintaan uang Keynes dan ekonomi Islam memiliki beberapa kesamaan dan perbedaan, Keynes menyoroti bagaimana suku bunga mempengaruhi kebutuhan uang, Sebaliknya, ekonomi Islam didasarkan pada prinsip-prinsip syariah. Fokus utama dari penelitian ini adalah untuk memahami sejauh mana relevansi konsep uang Keynes dengan ekonomi Islam. Hal ini akan meningkatkan pemahaman tentang bagaimana teori Keynes dapat diterapkan pada ekonomi Islam. Penelitian ini menerapkan metode penelitian kualitatif (library research), yang berfokus pada pemahaman dan pembelajaran teori dari berbagai sumber kepustakaan. Data dikumpulkan dengan melakukan pencarian informasi dari berbagai sumber seperti buku, jurnal, dan penelitian sebelumnya yang tersedia. Temuan dari riset ini menunjukkan teori Keynes tentang jumlah permintaan uang memiliki relevansi dalam konteks ekonomi Islam, meskipun terdapat perbedaan dalam prinsip-prinsipnya. Menurut teori Keynes, permintaan motif uang dapat dipengaruhi oleh berbagai faktor seperti alasan melakukan transaksi, cadangan, dan alasan berspekulasi. Meskipun motif tersebut relevan dalam ekonomi syariah, namun tidak digunakan secara khusus, dan terdapat aspek lain seperti ketaatan pada hukum syariah, ketaatan pada riba, dan pertimbangan pertimbangan moral dan etika dalam kegiatan ekonomi. Dengan demikian, pemahaman teori Keynes dapat diterapkan dalam konteks ekonomi syariah dengan tetap menjaga nilai dan prinsip Islam.

Exploring Technology Integration in Education: Lecturers Perspective on Outcomes-Based Education Platforms
Authors: Kasih Julianti , Wasis Galih Wicaksono , Bunyamin Hendra
Published: May 2024

Informatics education is evolving rapidly through the adoption of Outcome-Based Education (OBE), necessitating a rigorous investigation into the effectiveness of the implementation. This study was conducted using the advanced Unified Theory of Acceptance and Use of Technology (UTAUT)-3 model to assess the potential of OBE systems in enhancing teaching and learning processes. The study integrated a comprehensive set of nine variables to measure the acceptance level of OBE systems among lecturers at Maranatha Christian University Bandung and Universitas Muhammadiyah Malang. UTAUT-3 provides a more explicit understanding by incorporating Hedonic Motivation (H.M.), Habit (H), and Personal Innovativeness (P.I.). The Model also integrated the core constructs of Performance Expectancy (P.E.), Effort Expectancy (E.E.), Social Influence (S.I.), Facilitating Conditions (F.C.), Behavioral Intention (B.I.), and Users Behavior (U.B.). The result showed that B.I. was a central determinant of U.B., suggesting users' preparedness to engage with OBE systems.Furthermore, the routine use of technology as Habit (H) was closely related to Behavioral Intension (B.I.), showing that familiarity with technology facilitated the intention to adopt OBE systems. The result showed that UTAUT-3's comprehensive framework was superior in evaluating educational technology adoption due to its ability to account for users' engagement as Hedonic Motivation (H.M.), dispositional tendencies toward Personal Innovativeness (P.I.), and the critical role of established habits. Consumers' actual experiences and technological proficiency significantly influence adoption rather than individual characteristics. Therefore, UTAUT-3 was a more effective tool for predicting and understanding the Acceptance of OBE systems, guiding educational institutions toward successfully integrating information systems in learning environments.
Pre-clerkship Exploration of Underrepresented Specialties: Participant Perceptions
Authors: Dow Todd , Pouramin Panthea , Smyth Mike , Haupt Sebastian
Published: May 2024

Background: Background: Exposure to specialties significantly influences medical student career decisions; however, many students feel they are not adequately introduced to particular specialties until the end of their undergraduate training, if at all. Therefore, the Pre-clerkship Residency Exploration Program (PREP) was established. PREP was designed to reduce concerns regarding career decisions, while increasing exposure to specialties that traditionally receive less exposure in medical school curricula. Methods: PREP was a two-week elective available to second year medical students (n = 40) comprising five components: clinical electives, panel discussions, procedural skills circuits, simulations, and specialty-specific workshops. Participants rotated through ten electives and engaged in panel discussions focused on career choices and decisions. Skills circuits and simulations introduced students to procedures and scenarios they could encounter during PREP elective rotations. Specialty-specific workshops were held by several departments to build interest and introduce students to under-represented specialties. Results: PREP was assessed using the Kirkpatrick model, a framework that evaluates the effectiveness of training. PREP significantly increased students’ comfort with making career decisions, while reducing concerns related to a lack of exposure to various specialties (p < 0.0001) and time constraints with determining career options (p < 0.0001). Furthermore, PREP directly impacted career aspirations with 80.6% of participants changing their top-three career choices after completing the program. PREP is a valuable addition to medical school education and offers a novel approach to supporting students’ informed career decisions as well as increase their exposure to specialties which are underrepresented in medical school curricula. Discussion: We are currently in discussion with several Canadian medical schools about implementing PREP at their universities. Future research will analyze if participation in PREP translates to increased application rates to underrepresented specialties. To accomplish this objective, we will follow cohorts of PREP participants through the residency matching process and compare outcomes with historical data.

Intrinsic Motivation and the Future of Professional Development across Genders, Qualifications, and Experience
Authors: Balida Don Anton
Published: May 2024

Contrary to expectations, a global survey of recent graduates found no direct link between participation in Continuing Professional Development (CPD) and their self-determination or motivation. Despite diverse backgrounds and consistent high intrinsic motivation, the study challenges traditional assumptions about motivation being solely driven by CPD. This highlights the inherent value individuals place on professional development, potentially driven by personal growth aspirations or intellectual curiosity. The lack of a direct CPD-motivation link suggests a crucial shift towards more holistic development strategies. Beyond just technical skills, incorporating soft skills training, leadership development, and emotional intelligence workshops could create well-rounded professionals equipped for the modern workplace. The consistent self-determination levels across diverse groups imply receptiveness to guidance and support. Exploring the potential of mentorship programs could be highly beneficial, offering personalized advice, career guidance, and role models, potentially boosting intrinsic motivation and career satisfaction. This study paves the way for a more effective professional development framework that prioritizes intrinsic motivation, fosters a love for learning, and offers flexible learning avenues catering to individual preferences and styles. Incorporating technical skill development, soft skills training, mentorship opportunities, and tracking progress holistically, organizations and individuals can move beyond a transactional view of CPD and unlock its true potential: fostering not just technically skilled professionals, but also self-determined, intrinsically motivated individuals ready to thrive in the ever-evolving workplace.
Grønlands særlige foranstaltningsdømte.
Authors: Rømer Mette , Lauritsen Annemette Nyborg
Published: May 2024

Unlike legal systems in Denmark or many other countries, the Greenlandic Penal Code does not include the concept of punishment. Instead, the Code contains several diverse sanctions intended to prevent reoffences through treatment. This article explores this particular legal structure by examining cases of Greenlandic citizens sanctioned for treatment with or without deprivation of liberty. Based on an archival study of records held by the Prosecutor’s Office of the Greenland Police, this article maps the number of Greenlandic citizens sanctioned for treatment with or without deprivation of liberty in either Greenland or Denmark along withthe assessment of their mental state and place of treatment. The findings show that 49 of the 160 individuals convicted were sent to Denmark for treatment and rehabilitation within the prison service, forensic psychiatry, or forensic intellectual disability services. The most common types of crime among the convicted were violent. This article recommends that a new registration practice is needed to methodologically generate a representative picture of the convicted population.
Patientinddragelse i det grønlandske hospitalsvæsen
Authors: Seibæk Lene
Published: May 2024

While the Greenlandic National Health Service aims to involve citizens in the prevention and treatment of illnesses, it remains unclear how such patient involvement can be understood, developed, and implemented in contemporary hospital care. As part of a larger study, this article contributes to filling this gap in knowledge by identifying and discussing drivers and barriers to patient involvement in a Greenlandic hospital care context. It draws on empirical data generated from 2018-2020 via semi-structured research interviews and field observations at Greenland’s national hospital in Nuuk, Dronning Ingridip Napparsimavissua. Atotal of 11 patients and 14 healthcare professionals were included in this study to ensure variation regarding age and sex, patients’ diagnoses, place of residence, and other socio-demographic factors. Healthcare professionals were also invited to participate based on their medical specialty and experience. Observations of bedside care situations and other interactions between healthcare professionals and patients, including informal conversations, were conducted. Findings were analysed using Malterud’s systematic text condensation, constituting the following themes: ’Patients’ perspectives on the organization of care’; ’Health professionals’ perspectives on the organization of their work’, and ’Organizational barriers to patient involvement’. Based on a critical discussion of these findings, it is concluded that patient involvement will not be accomplished by simply focusing on patients’ health competencies and actions. To ensure that hospital care is provided in real partnership with patients and families, it is crucial that patient treatment is reorganized to include a more patient-oriented approach, and that healthcare professionals become aware of the significance of patients’ perspectives and develop new skills to integrate humanistic healthcare into their clinical practice.

Superconducting nanowire single-photon detectors (SNSPD) have the advantages of high maximal counting rate (MCR), high detection efficiency, and low dark count rate. They play an important role in the fields of optical quantum communication, optical quantum computing, laser ranging, and imaging. The MCR (i.e. detection speed) of SNSPD can be affected by the front-end readout circuit. To increase MCR, it is usually necessary to use a cryogenic DC-coupled readout circuit with a broad bandwidth. This study reports an SNSPD cryogenic DC-coupled amplification readout circuit based on a commercial high-speed operational amplifier chip OPA855. We systematically characterize its performance parameters in a temperature range from a room temperature of 300 K to a low temperature of 4.2 K. We address the problem of bandwidth loss of the circuit in a low-temperature environment by increasing the operating voltage of the OPA855 chip. For example, at 40 K, the operating voltage increases from ±2.5 V to ±4.9 V, and the quiescent current is about 8 mA, which is equivalent to a power consumption of 78 mW; meanwhile, the gain of this readout circuit is 16.7 dB, and the –3 dB cutoff bandwidth is ~2.7 GHz. We further install a cryogenic DC-coupled readout circuit based on the OPA855 amplifier at 40 K and characterize the performance parameters of the SNSPD at 2.2 K, such as the switching current, system detection efficiency, and MCR. The comparison with the conventional AC-coupled readout circuit at room temperature shows that the MCR increases about 1.3 times after using the DC-coupling circuit. Our study provides the interesting information about the OPA855 amplifier’s performance at low temperatures which facilitates its application in cryogenic environments and related fields.

A Brief Review of Varicose Veins in the Upper Limb from an Ayurvedic Perspective
Authors: Bobade Shubham , Asutkar Sheetal , Kadav Amar
Published: May 2024

Varicose veins typically occur in the lower limbs, caused by valvular insufficiency leading to the swelling and tortuosity of subcutaneous veins. Although rare in the upper limbs, they can be successfully diagnosed and treated. Rare causes include congenital vascular anomalies like Klippel-Trenaunay syndrome and Parkes Weber syndrome, characterised by Arteriovenous (AV) fistulae. Subclavian vein thrombosis-induced venous outflow obstruction is another uncommon cause. Diagnosis involves a thorough history taking with clinical examination, often supplemented by investigations. Invasive procedures are rarely necessary but may be used in unique cases to define the pathology further. Treatment for upper limb varicose veins closely mirrors lower limb approaches. The stab-avulsion technique combined with stripping of lengthier sections yields outstanding cosmetic and functional results. Surgical ligation with stripping effectively eliminates varicosities with a low risk of recurrence. Sclerosing agents like Sodium Tetradecyl Sulphate and Polidocanol are substitutes for surgery. In cases of varicosities resulting from upper limb arteriovenous fistulae, surgical intervention involving ligation of the distal venous limb or division of the fistula is the standard approach. In summary, while upper limb varicose veins are exceptionally rare, they can be accurately diagnosed and effectively treated with surgical interventions similar to lower limb varicose veins.

Authors: Monteiro Joswita , Adarsh KM , Dabholkar Amita Digambar
Published: May 2024

Introduction: Advancements in Computed Tomography (CT) have been continuously updated with the intravenous administration of contrast media, which enhances the visibility of internal organs and structures in CT scans. Contrast media administration often alters blood pressure. Aim: To observe the blood pressure variations among patients undergoing Contrast-enhanced Computed Tomography (CECT) thorax and Non Contrast Computed Tomography (NCCT) thorax. Materials and Methods: A cross-sectional study was conducted at the Department of Radiodiagnosis and Medical Imaging at Yenepoya Medical Hospital, Deralakatte, Mangaluru, Karnataka, India from February 2022 to August 2022. Patients who underwent examinations of NCCT thorax and CECT thorax within the age group of 20-80 years, involving 62 participants (31- CECT, 31- NCCT) were included. Intravascular contrast material was administered to the patient during a CECT thorax scan. One reader independently recorded the Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) five minutes before and five minutes after the venous phase in the CECT thorax and five minutes prior to and five minutes after in the NCCT thorax group.. A paired t-test was used for the comparison of SBP and DBP within the group. Results: The mean SBP before the scan was 120.7 mmHg {Standard Deviation (SD)=13.6} and after the scan was 130.7±12.1 mmHg. The mean DBP before the scan was 78.9±8.9 mmHg, and after the scan was 84.2±12.0 mmHg, respectively, before and after the injection of contrast. Therefore, a significant difference was found in the mean SBP and DBP before and after the injection of contrast within the CECT thorax group. Conclusion: There was an increase in blood pressure in patients who had undergone CECT thorax in both males and females. Hence, evaluating BP will provide awareness of different risk factors that can be caused due to the administration of contrast media
Spontaneous Perforation of Ascending Colon Presenting as Retroperitoneal Abscess: A Case Report
Authors: Kumar Davinder , Kumar Ritesh , Gupta Monika , Gupta Piyush , Marwah Sanjay
Published: May 2024

Perforation of the colon is frequently encountered in surgical emergencies and requires urgent intervention. Free colonic perforations are diagnosed early due to the development of signs of peritoneal irritation. However, perforation of the posterior wall of the colon into the retro-peritoneal space poses a diagnostic challenge because of the absence of signs of peritoneal irritation and its atypical clinical presentation. The authors reported an unusual case of 42 years old female patient with idiopathic perforation of the posterior wall of the ascending colon that presented as a large retroperitoneal abscess. The abscess was diagnosed based on clinical and Computed Tomography (CT) findings, and the patient underwent incision and drainage of the abscess through a flank incision. There was initial improvement in the patient’s general condition, but on the fourth day, there was faecal discharge through the wound, indicating colonic perforation. The patient was immediately taken for an emergency laparotomy. Intraoperatively, the peritoneal cavity was found to be clean; however, upon mobilisation of the ascending colon, two large perforations on its posterior wall were found with faecal soiling of the retroperitoneal tissues. Right hemicolectomy with end ileostomy and closure of the transverse colonic end were performed. Histopathology revealed the absence of any definite pathology, and a diagnosis of spontaneous perforation was made. This unusual case highlights that this rare possibility should be considered as a differential diagnosis of a retroperitoneal abscess to enable early intervention, which is likely to save the patient.

Authors: Alhenaidi Hala , Almalki Mohammed
Published: May 2024

This research explores the challenges encountered by staff at King Abdulaziz University Hospital (KAUH) in conducting health services research (HSR). A descriptive-analytical approach was employed, utilizing a structured questionnaire adapted from Karimian et al. [1]. A total of 334 staff members from an array of careers at King Abdulaziz University Hospital (KAUH) were involved in this study, representing diverse professional backgrounds. Among the 188 respondents with prior research experience, the study found that 83.5% of 188 respondents with prior research experience had conducted health services research, with 79.8% encountering difficulties. 52.1% had applied research outcomes in their practice, which was seen as an instrumental aspect of HSR. Findings revealed that the major obstacles included; administrative issues such as limited integration of research outcomes into practice and unfair evaluations (78%), followed, respectively, by professional challenges such as job burden, financial challenges with funding and budgeting, facility-related issues like outdated research databases, and obstacles related to research skills. Additionally, the findings revealed a significant difference (P<0.05), with academic staff facing fewer professional obstacles than non-academic staff, and Saudi researchers reporting more professional obstacles than non-Saudis. The findings emphasize the importance of addressing financial and facility-related obstacles to facilitate the practical utilization of HSR in health policy and community health services. Enhancing funding processes, clarifying budgeting regulations, and improving the research ecosystem are essential to overcoming these challenges and harnessing HSR's potential to improve healthcare access, quality, and cost-effectiveness.

Published: May 2024

Potatoes are the fourth most important food crop in the world. Two thirds of them are consumed by humans, while the other third is used as animal feed, potato starch, and in the manufacturing of pharmaceuticals, textiles, adhesives, paper products, and other products. Two factorial Complete Randomized Design with two level of treatment combination was applied throughout the experiment. During the experiment, dehaulming and non-dehaulming practice was performed and the potatoes were stored in three different storage conditions (Cold storage, Bamboo basket and Gunny bags). The superiority of rotting was recorded in gunny bags followed by bamboo basket and cold storage. Similarly, maximum sprouting was observed in bamboo baskets with minimum in cold storage. The maximum final weight loss was observed in bamboo basket followed by gunny bag and cold storage. The superiority in greening was observed in gunny bags whereas minimum in cold storage. Non-dehaulmed potatoes showed maximum loss in observed parameters whereas dehaulmed potatoes showed minimum loss. The interaction effect of dehaulming and non-dehaulming with different storage conditions had significant effect in rotting at 20days and in sprouting at 40days whereas was non-significant in final weight loss and greening. Among all the storage conditions used, best result was obtained in cold storage with minimum storage loss. The farmers are suggested to use dehaulmed potatoes with the storage under cold store. As the potato was stored in 10-12 degree Celsius, there was no sweetness in the cold stored potatoes so preferred by the consumers for table purpose. Therefore, it is suggested to conduct similar research in different location using other varieties along with dehaulming practices.

Published: May 2024

Understanding Attachment Styles and Romantic Conflict Management Skills is crucial for addressing relationship challenges like recurring conflicts and communication breakdowns due to unresolved attachment issues, which can cause emotional damage and deteriorate relationship quality over time. This study explores the relationship between Attachment Styles and Romantic Conflict Management Skills in university students, with 350 college respondents providing a diverse sample. The study found that attachment styles particularly avoidant attachment have a slightly high level while romantic conflict management skills show variations in subscales with compromise and avoidance tending toward higher levels. The Spearman's rank correlation coefficient showed a weakly positive connection, rejecting the null hypothesis and highlighting the influence of attachment styles on romantic conflict management skills. Moreover, the linear regression analysis identified avoidant and anxious attachment as significant predictors of Romantic Conflict Management Skills, suggesting that these styles may play a role in determining how conflicts are resolved in relationships. These results improve our understanding of the relationship between college students' attachment styles and their ability to resolve romantic conflicts. The study suggests that institutions should offer workshops on communication, attachment styles, self-awareness, and conflict resolution to foster healthy student relationships and provide counselors with guidance. Future research should explore additional variables and use advanced sampling techniques.

Authors: Pooja . , Kumar J. , Manchanda P.
Published: May 2024

We developed an algorithm based on combination of regularization and wavelet collocation method to solve Fredholm integral equations of the first kind. As first kind Fredholm integral equations are often ill-posed problems, regularization method is implemented to convert it into an approximate well posed Fredholm integral equation of the second kind whose solution converges to the solution of the original problem. Then wavelet collocation method is applied to obtain the numerical solution of the resulting problem. We have applied proposed method using Legendre and Chebyshev wavelets to some examples and compared their efficiency.

Published: May 2024

Background and Objective: Substance use disorders (SUD) remain a major public health concern and represent a significant cause of morbidity and mortality. Our goal in this study is to explore and determine the effect(s) of employment-based contingency (EBC) on enrolling SUD individuals into treatment, the rate of treatment adherence, and the rate of post-treatment abstinence.
Methods: PubMed and Google Scholar search was conducted using the search terms ((substance use disorder) AND (unemployment)) OR (therapeutic workplace)), for randomized controlled trials (RCT) published between 2012 and 2022, reporting on participants between ages 18 and 65 years who use opioids, cocaine or alcohol.
Results: Seven RCT which met the criteria and addressed the study objectives had a total of 389 participants. Three RCT of the seven with 203 participants found EBC to positively impact the rate of enrollment to treatment with 100%, 92%, and 100% enrollment rates in the respective studies. Three articles with 172 participants found a higher rate of treatment adherence and retention to treatment among EBC participants compared to the control group. There was more naltrexone-positive urine in the EBC group compared to control (72% vs. 21%, with a p-value of .01), and 74% (EBC) vs 26% (control) participants completed treatment. Four articles with 238 participants found that EBC improved the rate of abstinence by over 50%, which is double the rate among the control group without EBC.
Conclusion: EBC is effective in improving SUD treatment enrollment, treatment adherence, and post-treatment abstinence, however, the efficacy may be dependent on how much is earned as an incentive.

The flowers represent the most sensitive, delicate and loving feelings that ours words cannot portray. In India, roses are an essential and popular flower. It is an ornamental herb planted for its visually appealing and long-lasting blossoms. India has ample sunshine, plenty of land and the availability of skilled labour, all of which contribute to our ability to cultivate flowers in various locations. The cut flower growing farmers were selected from the Bengaluru rural districts of Karnataka by employing the simple random sampling techniques. The Cobb-Douglas production function was employed to determine the resource use efficiency of rose farming in Karnataka. The results reveals that land, Farm Yard Manure (FYM), fertilizer and labour contributed positively to the flower production, while farmers followed closer spacing and used more Plant Protection Chemicals (PPC). FYM and human labour were the most significantly influencing variables in protected rose cultivation. However, PPC was negative but non-significant. The ratio of Marginal Value of Product to Marginal Factor Cost (MVP to MFC) showed that FYM, fertilizers and human labour were under-utilized in open-field cultivation, suggesting potential for higher use. In protected conditions, there is a scope to increase FYM, fertilizers and human labour to optimize returns from cut rose production. However, land use, planting materials and plant protection chemicals should be reduced to optimize returns in protected conditions. Reorganizing expenditure among resources based on MVP to MFC ratios is necessary to optimize rose production. This includes reducing the use of PPC and following wider spacing in open-field cultivation. India's rose farming industry can benefit from increased efficiency and resource utilization.
Two‐Dimensional Flow Over Airfoils
Authors: Plotkin Allen
Published: December 2010

The classical solution for the flow past a two‐dimensional thin airfoil is obtained by using the potential flow model. In spite of the simplifications in the governing equations and in the boundary conditions, the results are close to experimental results. The model predicts the lift slope of 2π and the location of the aerodynamic center at the quarter‐chord point. Results are also presented for a simple trailing‐edge flap model, indicating that the lift can be increased by such a trailing‐edge device. On the basis of the results of this analysis, a simple lumped vortex model is proposed, which can be used to estimate multi‐airfoil interactions and also for three‐dimensional numerical models.
Laminar Boundary Layers
Authors: Bernal Luis P.
Published: December 2010

The concept of boundary layer is central to understanding and prediction of viscous flow effects in high‐Reynolds‐number aerodynamics. Here we review classical boundary layer concepts and analysis techniques for two‐dimensional laminar boundary layers. The theoretical framework first introduced by Prandtl in 1904 is outlined. Important concepts like the boundary layer equations, vorticity dynamics, boundary layer separation, and the viscous–inviscid coupling are discussed. Exact similarity solutions are presented in detail to examine the effect of pressure gradient and to support approximate methods. The application to internal and external flows of one‐parameter approximate methods based on the Kármán integral equation is also discussed in detail. Two‐parameter approximate methods based on integral momentum and energy equations are introduced. The more recent development of aerodynamic design codes implementing coupled viscous/inviscid equations using two‐parameter integral formulations of the viscous problem is noted.
Turbulent Boundary Layers
Authors: Morrison Jonathan F.
Published: December 2010

Fundamental concepts concerning the scaling of the mean velocity, Reynolds stresses, and velocity spectra in turbulent boundary layers are considered and the concept of self‐similarity is introduced. Its limitations in terms of Reynolds number, spatial extent, and wave‐number range are identified. An understanding of the interaction between the inner and outer regions is essential for dealing with the scaling of near‐wall turbulence. “Inactive” motion is shown to be a first‐order, linear superposition of the inner and outer layers that corresponds to a ‘no‐interaction’ condition equivalent to the local‐equilibrium approximation. Prandtl's boundary‐layer approximation is discussed and a strategy for coping with boundary layers with more complicated boundary conditions is explained and some useful empirical formulations provided. These “extra rates of strain” not only necessitate some additional empiricism in turbulence models for RANS solvers, but also provide a framework around which their effects may be understood. Some key challenges are identified.
Unsteady Aerodynamics
Authors: Platzer Max F. , Jones Kevin D.
Published: December 2010

Abrupt aircraft maneuvers, flight in gusty air, or self‐excited vibrations of aircraft components generate aerodynamic phenomena which require an understanding of unsteady flow effects. It is the objective of this chapter to provide an overview of the major unsteady flow phenomena which may occur in low and high‐speed flight. Also, it is shown that a full understanding of aerodynamic lift generation is linked to an understanding of the vortex generation phenomenon. The equations needed to analyze various unsteady flow effects are presented and an overview is given of the major analysis methods which have been developed over the years. They range from linearized potential flow methods to modern methods of computational fluid dynamics for the prediction of unsteady viscous and separated flow effects.
Aerodynamic Flow Control

Published: December 2010

Active flow control (AFC) has re‐emerged as a formidable research area in aerodynamics; this chapter provides a broad overview of modern developments. The control of large coherent structures via periodic perturbations and the mechanical means to achieve this have been at the heart of these developments. AFC has been demonstrated in wind tunnels over a 4 order‐of‐magnitude Reynolds number range and at high subsonic Mach numbers. Recently, an active flow control system for tiltrotor download alleviation was successfully flight tested. Most of the AFC research has focused on airfoil configurations including so‐called simplified high‐lift systems, although drag reduction, three‐dimensional configurations and flows, are also actively researched. Experiments that elucidate new aspects or isolate controlling parameters are considered to be invaluable for advances in the foreseeable future. Concurrently, the development of effective, robust, and system‐efficient actuators and sensors will determine the scope of applications. Computational fluid dynamics (CFD), with various levels of turbulence model complexity, is the primary tool for prediction of these flows. Coordinated experiments designed specifically for CFD validation will be invaluable for developing these codes. Recent progress in the arena of simulation methods such as direct numerical simulation (DNS), large eddy simulation (LES), and hybrid Reynolds‐averaged Navier–Stokes (RANS)/LES is expected to continue. Nevertheless, due to the expense of these methods, effort should also be expended in improving RANS predictions.
Aerodynamic Benefit of Aircraft Formation Flight
Authors: Gopalarathnam Ashok
Published: December 2010

The improved aerodynamic efficiency of formation flight is a result of induced drag reductions when multiple wings fly in close lateral proximity to one another to take advantage of the upwash fields of neighboring wings. The spacing in the streamwise direction, however, can be sufficiently large for safe flight operations. Maximum drag benefits are seen when neighboring wings in a formation have a lateral overlap of approximately 10% of the span. Theoretical studies of elliptically loaded wings in formation show that induced drag reduction ranges from 44% for two wings to 81% for 25 wings. V‐shaped formations, often seen in flocks of migrating birds, result in equal distribution of the drag benefit amongst all the individuals. Formation flight has the potential to result in significantly reduced fuel burn even when applied to existing aircraft and routes.
Shock Boundary Layer Interactions
Authors: MacManus David G.
Published: December 2010

This chapter introduces some of the basic aerodynamic features that arise from the mutual interaction between a shock wave and a viscous boundary layer. Various interaction types are presented, which initially focus on two‐dimensional flow fields. The main characteristics in terms of the flow topology, separation criterion, interaction length, and flow physics are discussed. It further extends the discourse to briefly introduce the more complex aspects associated with the unsteadiness of the interaction. Finally, the chapter presents some of the basic parameters and flow features associated with a three‐dimensional flow for a swept shock boundary layer interaction.
Compressibility Effects in Rotorcraft Applications
Authors: Pahlke Klausdieter G.
Published: December 2010

Compressibility effects play an important role in rotorcraft applications. They limit the high‐speed performance of rotorcraft because of wave drag, and they are the reason for the emission of high‐speed impulsive noise. Furthermore, compressibility triggers flow separation on highly loaded rotors in forward flight (dynamic stall).
