Published: July 2024

This study aims to evaluate the effectiveness of applying a group approach in counseling adolescents to address changes in their behavior. The research method used was quasi-experimental with a pre-test and post-test design to measure behavior changes before and after the group counseling intervention. The research sample consisted of 30 adolescents randomly selected from several high schools in city X using probability sampling methods. The group counseling intervention was conducted over 8 sessions, with each session lasting 90 minutes. Counseling topics included emotional control, communication skills, stress management, and confidence building. Data collection instruments included validated and reliable questionnaires, as well as direct observation by facilitators. Data obtained from the pre-tests and post-tests were analyzed using paired t-tests to determine if there were significant changes in adolescent behavior before and after the intervention. The data analysis results indicated significant positive changes in adolescent behavior after participating in group counseling. These changes included improvements in emotional control, better communication skills, more effective stress management, and increased self-confidence. Additionally, adolescents showed a more positive attitude toward themselves and their social environment.
Dasar Keilmuan Bimbingan Konseling dalam Perspektif Filsafat Ilmu (Ontologi, Epistimologi dan Aksiologi dalam Bimbingan Konseling)
Authors: Bunda Indah Permata , Sufyarma Sufyarma , Karneli Yeni
Published: July 2024

This research aims to explore the scientific foundation of counseling guidance from the perspective of the philosophy of science, focusing on three main aspects: ontology, epistemology, and axiology. In the ontology study, this research analyzes the nature and existence of entities that are the objects of counseling guidance, such as individuals, psychological issues, and the process of behavioral change. Epistemology in counseling guidance examines how knowledge about counseling is acquired, validated, and applied, encompassing the scientific approaches, theories, and practices used by counselors. The axiological aspect examines the ethical values and objectives underlying the practice of counseling guidance, including the role of moral values, professional ethics, and the social impact of counseling. This research uses a qualitative approach with literature analysis as the main method. The results indicate that the scientific foundation of counseling guidance is greatly influenced by an ontological understanding of humans as complex and dynamic beings, an interdisciplinary epistemological approach, and an axiological commitment to individual and community well-being

Authors: Qbilat Malak
Published: July 2024

This paper presents an exploratory study of accessibility in both Human Computer Interaction and Human Robot Interaction focusing on its intersection with interrelated concepts such as usability and inclusive design. It underscores the overreaching goal of these concepts in improving the user experience and provide equal access to all user interfaces, albeit with different targeted user groups. Furthermore, the study presents a short review on main accessibility laws and developers guidelines for both Human Computer Interaction and Human Robot Interaction. The review reveals a remarkable gap in accessibility laws and guidelines for Human Robot Interaction, hence, there is an urgent need to broader initiatives and efforts from authorities, researchers community, and industry stakeholders to formulate and create accessibility laws and developers guidelines pertaining to Human Robot Interaction products, where no such laws or guidelines were found in this study, except an individual initiative by the author, which includes a proposal dedicated to help developer in creating accessible interfaces for Socially Assistive Robots. This paper also discusses some practical challenges in implementing accessibility guidelines in HCI and HRI interfaces.

The syndrome of prolonged productive cough in children, which is not related to diseases of the ENT organs, is one of the urgent problems that arise in the practice of pediatricians, general practitioners and children's pulmonologists. Today, in the available foreign literature, there are many publications and practical recommendations, where chronic bacterial bronchitis, manifested by the presence of chronic wet cough in children, is described, which is one of the important diseases manifested by the presence of chronic wet cough in children. However, unfortunately, there is practically no information about this problem in Kazakh publications. The purpose of this descriptive review is to provide information to practicing doctors and students about chronic bacterial bronchitis in children. The article is devoted to the topical issue of etiology, pathogenesis, clinical, diagnostic criteria, differential diagnosis and treatment of chronic bacterial bronchitis in children. Prognosis and methods of rehabilitation are also discussed in the review.

Elevated serum uric acid (UA) concentration is considered to be as one of the factors contributing to endothelial dysfunction. However, it does not lead to clinical manifestations, so it is called asymptomatic hyperuricemia (ASH). The purpose of research was to study the effect of ASH on arterial hypertension (AH) followed by its correction.The investigation was held from 2018 to 2019. The prevalence and degree of severity of ASH were studied in 1018 patients with AH. Hyperuricemia was discovered in 78 patients, which was 7.7% of the total number of studied patients. Methods. A retrospective analysis of patients with AH undergoing inpatient treatment was performed. The control group of patients received standard hypotensive therapy. Although, the main group received standard therapy combined with urate-reducing therapy. Results. Comparative analysis showed that hypotensive therapy was effective in both investigated groups. By the way, index of the main group experienced better results, i.e., the systolic blood pressure (SBP) decreased by 18 Hg (11.6%) compared to the control group. In terms of diastolic blood pressure (DBP), it is dropped by 11.8 Hg (12,1%). The positive effect of urate-reducing therapy is the reason for rising efficiency of the therapy at all. Moreover, significant decrease of UA level was experienced from both researched groups. It averaged 38,3 mmol/l, which is 39.2% of the original result. Conclusion. Thus, the adverse effect of ASH on BP in patients with AH can be compensated by prescription of additional urate-reducing therapy to hypotensive drugs, which helps to reduce the adverse effect of ASH. The obtained data should be taken into account when physicians implement a disease management program.
Analyse comparée de la structure de néologismes de la langue des signes française (LSF) et de la langue des signes québécoise (LSQ) : Procédés de création et unités sublexicales
Authors: Gagnon Laurence , Parisot Anne-Marie , Strasly Irene
Published: July 2024

Nous proposons une comparaison de la structure sublexicale des néologismes de deux langues des signes (LS) : 99 du domaine de l’astronomie en LSQ et 85 du domaine biblique en LSF. Les objectifs de cet article sont de présenter i) une description des procédés de création (composition, dérivation, emprunt) et, ii) une analyse de la relation entre la structure interne (les unités sublexicales) des néologismes et leur sens, afin de déterminer si les unités sublexicales sont sémantiquement motivées dans une langue des signes. Basé sur van der Hulst et van der Kooij (2006), nous avons décrit les constituants selon leurs traits de forme (configuration manuelle, lieu et mouvement) et leur apport sémantique. Les 4 facteurs considérés pour l’analyse (régression logistique et khi2) sont les traits phonologiques (5 traits de forme de la main, 2 de lieu et 5 de mouvement), les caractéristiques sémantiques (motivé, non motivé), la langue (LSQ, LSF) et les domaines sémantiques (astronomie, bible). Les résultats montrent que les deux lexiques se distinguent par la fréquence de la composition (LSQ) et de la dérivation (LSF) ainsi que par la motivation sémantique de leurs unités sublexicales. Tous les traits sublexicaux sont significativement porteurs de sens dans le lexique de la LSF alors que la configuration manuelle seule est statistiquement représentative du référent pour le lexique de l’astronomie en LSQ.
Four kinds of lexical items: Words, lexemes, inventorial items, and mental items
Authors: Haspelmath Martin
Published: July 2024

This paper gives an overview of four senses of the terms “lexical (item/entity)” and “lexicon”, as well as several senses of the term “lexicalization”. That these terms are used in different senses in the literature has been discussed before, and it has been noted that this polysemy is sometimes confusing, but here I provide not only concrete definitions of word(-form) and lexeme and succinct discussion of the relevant issues, but I also propose two new terms: inventorium (the unpredictable elements of a language) and mentalicon (the elements that a speaker stores in memory). The latter two are crucially different because all speakers store many predictable elements. The four different senses can thus be distinguished clearly by using the four terms word-form, lexeme, inventorial item, and mental item. In the final section of the paper, I note that the term lexicalization also has multiple senses, but its most important sense is inventorization.

Aboriginal Students’ Achievement in Science Education: The Effect of Teaching Methods
Authors: Bourque Jimmy , Bouchamma Yamina , Larose François
Published: July 2024

Some authors assume that the academic difficulties encountered by Aboriginal students can be partly explained by the discrepancy between teaching methods and Aboriginal learning styles. However, this hypothesis lacks empirical foundations. Using pan-Canadian data, we tried to identify the most efficient teaching methods for Aboriginal students and assessed whether these methods were associated with performance differences between Aboriginals and non-Aboriginals in science education. Results revealed that judicious dosage and a proper balance among teaching methods seem to be required for students’ optimal achievement. In addition, only marginal differences were observed between Aboriginals and non-Aboriginals. However, standard assessment methods might partly explain these unexpected results.
Academic Advisors as Valuable Partners for Supporting Academic Integrity
Authors: Javeed Shehna
Published: July 2024

Academic Integrity is a fundamental value in higher education. Due to the increased ease of access to all types of information through social media and the internet, the lines have become blurred on what is can be “borrowed” and used. Recent proliferation of contract cheating has only reinforced that integrity cannot be just the responsibility of the Dean’s Office or the Academic Integrity offices. Advisors and learning strategists who see students regularly, can ubiquitously play a valuable role in integrating academic honesty into their conversations and workshops. This can be achieved in collaborations with campus partners on campus wide programming, starting early with integrating the conversation about honesty in academic orientations for new students and parents, and when having difficult conversations about study success and academic decision-making.
Is this in my contract?: How part-time contract faculty face barriers to reporting academic integrity breaches
Authors: Crossman Katherine
Published: July 2024

A holistic approach to academic integrity in higher education requires a concerted and integrated effort of all stakeholders across campus, yet the tiered faculty system of most institutions may be at odds with comprehensive approaches. This paper explores how part-time contract faculty (also known as “sessionals” in Canada) face barriers to reporting student breaches of academic integrity. Drawing on scholarly literature, as well as my experiences as a sessional instructor, I explore this topic. In particular, I note that the time commitment and emotional investment involved in reporting transgressions according to institutional protocol can be especially burdensome for part-time instructors. I conclude with recommendations to better support sessional instructors to foster academic integrity.
Proactive not punitive: Approaching academic integrity from an educational perspective
Authors: Liang Ann , Maddison Tasha
Published: July 2024

Our implementation of Turnitin Similarity Software at Saskatchewan Polytechnic strengthened the overall support services for both faculty and students in preventing plagiarism. Using a holistic approach we drew on the collective intelligence of experts from several departments, which resulted in training sessions, curriculum design support and intensive student support. Our research used a variety of methods such as a literature review, quantitative data from user surveys, results from the similarity software and qualitative data from focus groups that center on perceptions of the issue within the program and the perceived benefits of the software. Highlights include the use of Turnitin as a writing improvement tool for students, shifting the mindset of faculty from being punitive to being proactive, writing clear and consistent assignment instructions, embedding student supports, mandatory student and faculty training in Turnitin, academic integrity education, as well as protecting student rights and intellectual freedom.
Ethics, EdTech, and the Rise of Contract Cheating
Authors: Clarke Gray Brenna
Published: July 2024

This talk traces the connections between the unethical use of algorithms, inattention to issues of equity and access, and failures of data privacy to the rise of contract cheating. The reported experiences of instructors and students tell us that contract cheating firms mine student data and exploit existing relationships between students and their educational technologies in order to find new clients and to extort the ones they already have. These companies use algorithmic searches of social media to track down vulnerable students, and once granted access to a closed educational context like Moodle, approach more students in the course or institution, which is how the use of these services seems to multiply by orders of magnitude within an institution. Once these companies have student ID and credit card information, they often engage in financial exploitation of students. Research demonstrates that many of the educational conditions that drive students to seek out contract cheating firms — lack of guidance on assignments; high-stakes assessments without appropriate scaffolding; personal or financial crises — are also conditions that do not promote learning. This talk argues that the epidemic of contract cheating can be insulated against by a renewed attention to ethical pedagogical strategies in the deployment of educational technologies. Given the explosive growth of the contract cheating problem and the huge money it makes for unethical players, it is imperative that post-secondary institutions protect students by all possible means. Limiting for-profit vendor access to student data, avoiding course-in-a-box homework system approaches to education, and using open pedagogical strategies to design persistent, non-disposable assignments are critical strategies in the fight against contract cheating, as is educating students and faculty about the importance of data security and privacy.
Insights on Academic Integrity Policy Development: Crafting Policy Catered to Your Institution
Authors: Al-Haque Rashed
Published: July 2024

The purpose of this session is to highlight the opportunities and challenges of crafting an academic integrity policy that is responsive to an institution’s unique needs and character. A robust and comprehensive policy is crucial to upholding the values and principles of academic integrity within higher education.
Over the course of two years (2018-2020), Camosun College’s Office of Education Policy and Planning worked with stakeholders from across the college to develop its new academic integrity policy and procedures. The work led to an extensive overhaul of the college’s academic integrity policy along with a review of its associated procedures intended to address and appeal allegations of academic misconduct. The end result is a clear policy and set of procedures that appropriately balances the rights and responsibilities of students, faculty, and administration.
The presentation will focus on sharing strategies on how to engage institutional stakeholders in a meaningful way to develop an academic integrity policy for your college/university. Emphasis will also be placed on what supports and resources are required to implement an academic integrity policy and insights from how policy implementation is going so far at Camosun.
Cheating: It depends how you define it
Authors: Kennette Lynne N. , Jelenic Milan
Published: July 2024

Cheating in academia is defined multidimensionally and might include dishonesty, fraud, stealing, and unauthorized use. This behaviour appears to be on the rise in higher education, though it may be somewhat subjective. Beyond the ethical issue of cheating, inadequately learned skills and unqualified practitioners put lives at risk (e.g., medicine, engineering), as well as the institution’s reputation and integrity in producing proficient graduates. We asked Canadian students and faculty from a two-year college to define academic cheating in their own words and rate a number of behaviours to indicate their perception of whether the behaviour should be considered cheating or not. Overall, there was a great overlap between the themes evoked in students’ and faculty’s definitions of cheating. Differences between students’ and faculty’s ages might suggest a different degree of moral reasoning which may have impacted the responses. This study further contributes to knowledge about cheating because we surveyed college students (rather than university students), which are greatly under-represented in the literature.
Building a Culture of Academic Integrity through Restorative Justice
Authors: Abramson Alana , Rucker Anna
Published: July 2024

Restorative justice (RJ) is a philosophy and set of values and principles that can inform justice practices and responses to harm. Its processes aim to address needs, repair or transform relationships, and promote understanding, meaningful dialogue, and direct accountability. Ethical and mindful approaches to RJ processes have the potential to address power imbalances, enhance community participation, establish relationship-based environments, and respond more meaningfully to human needs, which promotes social justice. A restorative lens has been applied to post-secondary environments in relation to academic and non-academic harms that occur on and off campus between students, faculty, and staff. This workshop will describe what we are learning through taking a restorative approach to building a culture of academic integrtity at Kwantlen Polytechnic University. Workshop participants can expect us to cover the following topics:* Describe the principles and procedures of restorative justice in relation to promoting a culture of academic integrity* Identify the benefits of restorative justice as an effective response to academic integrity violations compared to punitive approaches
Douglas Mastriano Scandal
Authors: Kuhn Roland
Published: July 2024

This case study looks at how a fraudulent PhD thesis from a Canadian university became entangled in US politics, attracting US and Canadian media attention. In 2013, Douglas Mastriano, a US Army colonel, was granted a History PhD from the University of New Brunswick (UNB) under unusual circumstances. A thesis committee member was removed without his consent, then informed by UNB that the thesis had been approved over his strong objections. UNB declared a 17-year-long embargo on public access to Mastriano’s thesis (it later admitted that its rules limit thesis embargoes to 4 years).
In 2014, Mastriano published a book based on his thesis. Respected historians found multiple instances of academic fraud in it, including falsification of archival information. Scholars who requested access to Mastriano’s thesis were rebuffed by UNB. There matters might have rested. However, in November 2022 Douglas Mastriano ran for Governor of Pennsylvania. A Donald Trump supporter and participant in the Jan. 6, 2021 US Capitol invasion, he often cited his PhD from UNB during his campaign. Under media pressure, UNB released his thesis in October 2022. So far, 213 cases of serious academic fraud have been found in it.
Before November 2022, UNB promised that “two independent investigators” would investigate Mastriano’s 2013 thesis and the 17-year-embargo on access to it. Subsequently, UNB has walked back that promise.
Attendees will learn about the practical and ethical issues faced by a Canadian university when an old case of academic fraud unexpectedly becomes a source of controversy in the media.
A Bayesian Approach To Locally Varying Regularization In Optical Flow Velocimetry
Authors: Jassal Gauresh Raj , Somersalo Erkki , Calvetti Daniela , Schmidt Bryan Eric
Published: July 2024

A recent method for determining accurate, dense velocity fields from a pair of particle images is to solve the optical flow problem, but the ill-posed inverse problem of optical flow velocimetry (OFV) generally entails minimizing a weighted sum of two terms--fidelity and regularization--and the weights in the sum are parameters that require manual tuning based on the flow properties and particle images. This tuning of the weighting parameters makes the experimental applicability of the method much more challenging as the calculated velocity field has demonstrated sensitivity to the value of the weights. This work proposes a hierarchical model for the weighting parameters in the framework of maximum a posteriori (MAP)-based Bayesian optimization approaches. The resulting method is tested on three different synthetic datasets and on experimental particle images. The method is found to be capable of self-adjusting the local weights of the optimization process in real-time while simultaneously determining the velocity field, leading to a more accurate estimate of the velocity field without requiring any dataset-specific manual tuning of parameters.
Enhancing Sensitivity And Quantifying Uncertainty Of Volumetric Two-Colour Two-Dye Laser-Induced Fluorescence Thermometry Of Aqueous Solutions
Authors: Kashanj Sina , Nobes David
Published: July 2024

Laser-induced fluorescence (LIF) is a nonintrusive method for temperature field measurement in gaseous and liquid flow fields. There has been attempts to enhance the temperature sensitivity of this method mainly by applying two fluorescent dyes with opposite temperature sensitivity. While there has been advances in enhancing the temperature sensitivity of LIF thermometry in aqueous solutions, there factors that limits the enhancement of the temperature sensitivity. This work explores the factors that restricting the temperature sensitivity in the ratiometric systems using Fluorescein and Kiton red dyes. The uncertainty resources associated to this ratiometric system is also investigated considering the application of this method in both planar and volumetric configurations.
A Single Camera Calibration-Free Approach For Dispersion Size Measurement Using Depth From Defocus
Authors: Rao Saini Jatin , Sharma Shubham , Basu Saptarshi , Tropea Cameron
Published: July 2024

The Depth from Defocus (DFD) imaging technique is used to measure the size and number concentration of particles in dispersed two-phase flows, but until now it has primarily been applied to low concentration particle images. This study explores how the technique can be extended to handle overlapping images caused by neighboring particles, significantly broadening the application scope of the DFD technique and enabling measurements at higher particle number/volume concentrations. The processing algorithms are experimentally validated using a dedicated apparatus that can systematically vary particle size, shape, and degree of image overlap. Additionally, this study explores the use of Convolutional Neural Networks (CNN) for this task, comparing these results with those obtained using conventional analyses in terms of accuracy, tolerable concentration limits, and computational speed. This approach requires a large teaching dataset of images, which is only practical and feasible if the dataset can be synthetically generated. An image generation procedure for out-of-focus neighboring spherical particles, resulting in a known blurred image overlap, is therefore first developed. This procedure is validated using laboratory images with known particle size distribution, position, and image overlap before creating the teaching dataset. The trained processing scheme is then applied to both synthetic datasets and experimental data, allowing the evaluation of the technique’s limits in terms of image overlap and tolerable volume concentration, as a function of particle size distribution.

Published: July 2024

In this study, we utilized high-speed photoelastic tomography to quantify dynamic stress fields within a soft substrate during droplet impact. This manuscript details the measurement technique, which employs a high-speed polarization camera and the principles of photoelastic tomography. Our method successfully enabled the quantitative measurement of dynamic stress fields in a soft substrate during droplet impact. Additionally, we conducted an analysis of the impact force derived through the spatial integration of the measured stress field. The discussion explored the interplay between the maximum impact force, droplet viscosity, and substrate elasticity. Our findings indicate that the maximum impact force 𝐹max can be expressed as a function with a self-similar variable of 𝑅𝑒 / 𝐶𝑎^2 , where 𝑅𝑒 is Reynolds number representing the droplet inertial force and droplet viscous force and 𝐶𝑎 is Cauchy number representing the ratio of the droplet inertial force and substrate elastic force. This combination, 𝑅𝑒 / 𝐶𝑎^2 , represents the relationship between the relaxation time of droplet and substrate deformation ( 𝜂/ 𝐸), the contact time of the droplet (𝑅 / 𝑉), and the ratio of substrate elastic force to droplet inertial force. Consequently, the maximum impact force 𝑅𝑒 / 𝐶𝑎^2 is determined by the balance between the relaxation and contact times. We believe that our developed method will significantly enhance the understanding of droplet impact phenomena. Furthermore, it holds potential for broader applications in various engineering processes, such as analyzing stress distribution in materials caused by liquid jet impact and studying cavitation bubbles in viscoelastic materials. This method's ability to provide detailed quantitative measurements of dynamic stress fields offers a valuable tool for future research and technological advancements in related fields.
Optical Temperature Field Measurements With Two-Color Laser Induced Fluorescence In A Stratified Thermal Energy Storage

Thermal energy storage systems (TES) are an important part for storing surplus electric energy from renewable, volatile energy sources. TES using liquid storage materials operate most efficiently by stratifying the storage fluid based on its thermal density gradient into a hot and cold layer, separated by a thermocline region. Previous studies of such stratified TES have shown that heat conduction from the hot, upper layer to the cold, lower layer through the storage tank wall induces counter-directed convective flows (wall jets) along the inner walls. These wall jets carry hot fluid from the upper layer and cold fluid from the lower layer towards the thermocline region, which leads to mixing of the layers and therefore to a decreased thermal efficiency. To quantify the influence of the wall jets on the mixing process, optical temperature field measurements in the thermocline region of a 105 L stratified TES model experiment are performed with two-color planar laser induced fluorescence (2C-PLIF). The results show that the method is feasible for evaluating the thermocline temperature distribution over time in such a system with an accuracy of 1.5 °C. Further measurements in the hot wall jet region show that the temperature resolution of the measurement system limits the evaluation of the thermal boundary layers. However, the 2C-PLIF system provides sufficient temperature field information to determine the local heat fluxes in future studies in combination with simultaneous PIV measurements.

Conditional sampling and averaging are valuable techniques for discerning and quantifying notable regions within turbulent flows. These methods have been particularly prevalent in experimental and numerical investigations of turbulent shear flows. Conditional statistics effectively analyze the dynamics and characteristics of turbulent flows, offering insights into transitional behaviors and distinct features within these regimes. This approach is instrumental in studying turbulent shear flows, such as jets or mixing layers, where a well-defined zone separates the turbulent core from the non-turbulent surrounding fluid. This zone, known as the Turbulent/Non-Turbulent Interface (TNTI), plays a crucial role in various phenomenological changes, including the transfer of mass, momentum, and scalar fluxes. While statistics in jet flows are often reported along the radial direction for a given downstream position, this method can obscure the underlying physical processes. Scalar dissipation rate, transport, or turbulent kinetic energy involve velocity or concentration gradients at the flow interface. To date, the impact of sampling direction on conditional statistics within jet flows has not yet been thoroughly discussed. This study focuses on determining gradient trajectories at the interface of turbulent flows. Gradient trajectories have been used to explore structures in turbulent flows, proving effective in analyzing homogeneous shear turbulence. This study introduces a methodology for sampling conditional data by computing gradient trajectories intersecting the TNTI. The primary objective is to verify whether sampling statistics along the gradient of scalar concentration provide a more detailed understanding of the processes occurring near the TNTI. The methodology involves computing a field of gradient trajectories from concentration fields obtained through Planar Laser-Induced Fluorescence (PLIF) in a N2/N2 jet with Re = 2900. Conditional statistics at the TNTI of a jet flow along the gradient trajectory for a given downstream position are calculated and reported. The paper aims to compare conditional statistics along gradient trajectories with those obtained along radial and normal directions at the TNTI. It is expected that gradient trajectory statistics align more closely with normal direction statistics near the interface and diverge as it gets into the jet or coflow fluid.

A series of refractive index-matched time-resolved tomographic PIV experiments are performed to study the dynamics of motion of solid spheres in flow. The refractive index matching of acrylic spheres with the working fluid facilitates unobstructed optical access around the spheres, enabling the simultaneous estimation of both the 3D flow field and the fluid-structure interactions governing the kinematics of the spheres. Additionally, using normal tracers as well as fluorescent tracers for PIV helps identify the most suitable approach for multiphase index-matched PIV studies. Two different test cases are presented: (1) solid spheres moving in a round channel with an abrupt area expansion and, (2) solid spheres rising in a quiescent flow at terminal velocity. Despite both falling under the category of solid-liquid flows, these cases exhibit entirely different mechanisms and flow characteristics. Nonetheless, refractive index matching provides a valuable tool that can be used to characterize the flow as well as the motion dynamics of the free spherical particles in a liquid. These time-resolved 3D experiments offer a comprehensive insight into the transient evolution of the flow fields and the pressure forces on the spheres, providing a complete picture of the dynamic process. The emphasis of the present paper lies in the experimental methodologies, challenges and data analysis techniques used for refractive index-matched multiphase flow studies.
Multi-Perspective Heterodyne Digital Holography For High-Speed Imaging Of Density Fluctuations In Supersonic Flow

Published: July 2024

Density fluctuation measurements with high spatio-temporal resolution provide meaningful insights into the dynamics of turbulent structures in shear layers, boundary layers, and disturbances that influence the transition to turbulence. The current contribution presents a new multiple perspective digital holographic imaging technique that aims to resolve high-frequency density fluctuations with spatial discrimination along the line of sight. A key element of the proposed method is the generation of a beamlet array of varying view angles that is spatially overlapped within the measurement zone. We present the first experimental realization of this approach using a 7-element hexagonally packed fly’s eye lens array and analyze results for a pair of mutually perpendicular and axially offset sonic jets. The experimental apparatus also incorporates heterodyne detection with a heterodyne frequency set to 1/4 of the imaging frame rate. The optical system performance is evaluated for a crossing jet flow and key design considerations for the multi-perspective optical system are discussed.
