Authors: Jinhui Kang , Tarofder Arun Kumar
Published: December 2023

Purpose: The purpose of this research is to analyze and evaluate factors affecting Chinese female consumers' purchase intention in Live streaming e-commerce

Theoretical framework: In the e-commerce live streaming room, anchors, products and scenes will affect the perceived value of consumers from multiple angles, and then affect the purchase intention. 

Design/methodology/approach: In order to examine the relationship between anchors, products, streaming room atmosphere, etc. women's purchase intention, we designed survey questions, tested ten hypotheses, and used regression analysis to summarize the research results. Research results: SPSS statistical software was used to investigate the correlation between independent variables and the above hypotheses by principal component analysis . It showed that there was a definite relationship between the communication mode of anchors, anchor popularity, anchor interaction, product value information, product price discount, brand awareness, brand awareness, Live streaming atmosphere and female purchase intention.

Research, Practical & Social implications: For all participants in live streaming e-commerce, it is necessary to fully understand what factors will affect the consumption willingness of Chinese women.

Originality/Value: Under the mode of "e-commerce + live network broadcast", academic research on the purchase intention or behavior of Chinese female consumers in live e-commerce broadcast is scarce. This paper draws relevant conclusions through a certain number of hypothesis tests, which is a supplement to the research on consumers' purchase intention under the background of network broadcast.
Exploring the Mediating Role of Customer-Company Identification: The Association Between Perceived Corporate Social Responsibility and Customer Citizenship Behavior
Authors: Bian Xiangyu
Published: December 2023

Customer citizenship behavior can not only reduce the production and marketing costs of enterprises, but also improve customer satisfaction and achieve long-term development. Taking the customers of Chinese Internet companies as the research object, this study aims to examine the role of customer-perceived CSR on customer citizenship behavior and to explore whether customer-company identification will act as a mediator in it. Through an empirical analysis of 832 Internet company customers, the results reveal a significant link between customer-perceived CSR and customer citizenship behavior. At the same time, the intermediary effect of customer-company identification also has a significant supporting role. Based on the findings of the study, the following management insights can be discerned: Internet companies should actively undertake social responsibilities. Companies should also strengthen communication with customers to enable customers to have a deeper understanding of the company's social responsibility commitments, thereby enhancing customers' sense of identification with the company. In addition, companies can consider creating incentives to encourage customers to engage in more citizenship behaviors.

Published: December 2023

In the present research work, the thermal comfort of an educational building in a semi-arid climate of Lahore, Pakistan has been analyzed based on the PMV-PPD method using a subjective scale in terms of acceptability, neutrality, and preference, considering the impact of gender. Firstly, this study examine how the temperature affects occupants\' (male and female) comfort levels in current university classrooms during the winter and summer. Secondly, how occupant behavior affects thermal comfort, productivity, and health well-being to determine how future buildings should be designed to accommodate gender preferences. Thirdly, the study improve retrofitting approaches for building systems that make it satisfies inhabitants\' thermal requirements, and is cost and energy effective. This study revealed that females were more affected by winter conditions while males were more affected by higher temperatures in summers. In both seasons, males found a frequent impact of thermal comfort, due to which more productivity loss was observed in them in comparison to females. In winter, females were more affected form SBS, and in summer, males showed more symptoms of getting affected by SBS. The overall percentage saving in energy consumption was found 27 % for considered Building compared with retrofitted simulated model of building systems. It is suggested that a well-insulated indoor thermal environment is the need of the hour for classrooms in university buildings to improve the thermal comfort conditions, productivity and health conditions of the occupants for both seasons.
Running a business in a multilingual community
Authors: Indongo - Haiduwa Julia
Published: December 2023

The study investigated the linguistic experiences of the women food vendors in the informal sector in Katutura who identified themselves as monolingual speakers of the Oshiwambo language. The aim is to explore how the business activities of these women are affected by their inability to speak an additional language. The aim was to establish how monolingual women manage to run their businesses in a multilingual setting. The study was qualitative and the instruments used consisted of a questionnaire that solicited the linguistic repertoires, biographic information and contact details of the participants and semi-structured interviews to discuss the participants’ language experiences concerning their business activities in the market. The study revealed that the participants were, in actual fact, not monolingual because they had knowledge of other languages in their repertoires; the participants’ business activities were not hindered by their inability to speak an additional language fluently because they mix words of the languages in their linguistic repertoire to communicate instead of speaking in one language.
effectiveness of health communicators advocating the use of pre-exposure prophylaxis (Prep) among men having sex with men (MSM) in Windhoek, Namibia
Authors: Lukas Frieda , Peel Clayton
Published: December 2023

This study assesses the effectiveness of caseworkers working with the Society of Family Health Namibia (SFH-Namibia) as health communicators in advocating the use of Pre-Exposure Prophylaxis (PrEP) among men who have sex with men (MSM).  The study assessed the outreach’s effectiveness in diffusing information about a medicinal product with HIV-preventative qualities, with urgency for its adoption among HIV-negative men who have sex with men because they are at a high risk of contracting HIV-AIDS. In-depth interviews were conducted with 12 respondents, of whom six were MSM, and six were caseworkers from SFH-Namibia. An additional 14 MSM respondents participated in a focus group discussion whose purpose was to record an honest exchange of views among MSM themselves on PrEP and its promotion. The general findings were that PrEP is winning cautious acceptance, with most adoptions influenced by the interventions of the SFH caseworkers, but others also benefitting after peer counselling from other MSM, mediated by channels such as WhatsApp. The importance of peer counselling among MSM especially using new media technology was a notable finding.
Protecting the Fairness of European Parliament Elections via Preliminary Ruling
Authors: G. Szabó Dániel
Published: December 2023

Supreme or constitutional courts regularly step in to protect the democratic process by deciding election disputes. It is remarkable that the Court of Justice of the European Union (CJEU) has so far barely been engaged concerning the European Parliament (EP) elections. Using Hungary as an example, I will argue in the following that the CJEU is institutionally well-positioned to help protect the integrity of the 2024 EP elections via preliminary ruling procedures. Hungarian democracy has been in decline, according to the EP, the Commission and various democracy indices. The problems include the lack of a level playing field, targeted action by authorities against opposition parties, overlaps between the activities of the government and the governing party, state funding of campaigning and party financing in general, lack of media pluralism, and the different means of voting for citizens living abroad (postal vote for some and not for others). I argue that the CJEU could and should be engaged to protect the fairness of the EP elections in Hungary.

Published: December 2023

Bu çalışmanın amacı, uluslararası suçlara yönelik kriminolojik yaklaşımları; Uluslararası Ceza Mahkemesi kapsamına giren uluslararası suçlar özelinde, Uluslararası Hukuk ve Kriminoloji alanlarının etkileşiminde işbirliği ya da dışlamaya neden olan girişim ya da kısıtları değerlendirerek, disiplinerarası bir bakış açısıyla çözümlemektir. Çalışma söz konusu alanların temel özelliklerine, kuramsal altyapılarına ve tarihsel süreçte yaşanan kırılmalara değinerek, literatürde baskın biçimde tartışılan kriminolojinin uluslararası suçları göz ardı ettiği iddiasını incelemiş ve kriminolojik yaklaşımların daha esnek ve eleştirel bakış açıları getiren ve karşılıklı kazanımlara odaklanan seyriyle uluslararası suçların çözümlenmesine yönelik Uluslararası Hukuk araştırmalarına giderek daha yakın konumlandığı görülmüştür. Ceza Hukuku’nun kriminolojik yaklaşımlarla ulusal düzeyde var olan yakın ilişkisi, uluslararası ve ulus-üstü çalışmalarda eksiktir. Bu eksikliğin giderilmesine ilişkin girişimler artarak devam etmektedir. Bu araştırma ulusal literatürdeki eksiği de göz önünde bulunduran, bu konudaki işbirliğine yönelik bir çağrı niteliğindedir. Çalışmada ayrıca, uluslararası suçlara yönelik kriminolojik yaklaşımların uluslararası suçların önlenmesine ilişkin katkıları değerlendirilmiş, her ne kadar mevcut sistem cezalandırma ve kovuşturmalar yönünden ciddi eleştirilere maruz kalsa da uluslararası suçların önlenmesi odağında kriminoloji alanıyla işbirliğinin olumlu sonuçlar vereceği değerlendirilmiştir.

Lightning and surge protection in intrinsically safe measuring circuits
Authors:   DEHN SE, Kienlein Manfred
Published: December 2023

Processing or transporting combustible substances can often lead to the creation of mixtures capable of forming an explosive atmosphere. Strict safety precautions must be in place when setting up and operating systems in which substances of this kind may be present. This is also set out in Directive 1999/92/EC [1], which addresses the user or employer. According to this directive, they are obliged to assess the explosion hazard posed by their system and they must ensure that all minimum regulations are complied with. Their tasks also include dividing the hazardous areas into zones, marking these areas and documenting all measures for protecting employees in the explosion protection document. In Germany, European Directive 1999/92/EC [1] is implemented in national law by the Ordinance on Industrial Safety and Health (BetrSichV) [2] and by the Ordinance on Hazardous Substances (GefStoffV) [3]. The technical directives for industrial safety (TRBS) and for hazardous substances (TRGS) set out the corresponding regulations in more concrete terms. They provide users with information about the risk assessment and recommend protective measures for the corresponding sources of ignition.
Emergency lighting

Published: December 2023

Even Europe, as highly industrialised as it may be, is not extensively protected against power failures. The increased use of renewable energy sources and the associated fluctuations in supply mean that additional power supply issues may arise. As a result, a standby power supply is an absolute must, both in public spaces and at business premises. Central battery systems as emergency lighting systems offer secure protection in the event of a power supply failure, safely providing the required lighting level even when the main supply network is unavailable.

تأثير الادارة المشتركة للموارد المائية لحوضي دجلة والفرات في امن واستقرار العراق
Authors:   كلية العلوم السياسية – جامعة بغداد, شرقي نهرين جواد
Published: December 2023

المصدران الرئيسان للمياه العراقية، هما نهرا: دجلة والفرات، اللذان يمدان (98٪) من المياه السطحية للبلاد. ينبع كلا النهرين من تركيا، ويتدفق نهر الفرات عبر سوريا، وبعض الروافد الأخرى تتدفق عبر إيران. كان العراق حتى السبعينيات يعدّ دولة غنية بالمياه، ولكن منذ أن بدأت تركيا في بناء السدود على النهرين، قللت بشكل كبير من موارد العراق المائية. إذ بدأت الحكومة التركية مشروع جنوب شرق الأناضول، ببناء (22) سداً و (19) محطة طاقة هيدروليكية للمقاطعات النامية في الجنوب الشرقي، وكانت مترددة في التفاوض بشأن صفقة مياه مع العراق وسوريا. تركيا لديها القدرة على قطع تدفق المياه في اتجاه مجرى النهر على المدى القصير، مع تقليل إمدادات المياه الإجمالية في العراق. على سبيل المثال، في التسعينيات، رفعت تركيا مستوى المياه في سد أتاتورك دون علم سوريا والعراق. كما أدت سياسات قطاع المياه في إيران إلى تقليص إمدادات المياه في العراق. إذ إنَّ الروافد التي تنبع من إيران توفر (40٪) من مياه شط العرب (نهر الوند) في العراق، وكان لبناء السد تأثير مدمر في تدفق المياه إلى المحافظات الشرقية من العراق. ومع بناء (600) سد في إيران والمزيد من التخطيط، تم تحويل مياه الأنهار مثل كارون والكرخة للبقاء في إيران، ولم تعد تتدفق إلى العراق. هذه الانحرافات في المسار لم تقلل من تدفق المياه إلى العراق فحسب، بل أدت أيضًا إلى زيادة ملوحة المياه. ففي محافظة البصرة وحدها، تم إدخال (118) ألف شخص إلى المستشفى في صيف 2018، بسبب مشكلات صحية تتعلق بجودة المياه. بالنظر إلى المستقبل، من المتوقع أن يجف نهرا: دجلة والفرات داخل العراق بحلول عام 2040 بسبب سياسات المياه لجيرانه، ويبدو أنَّه ليس ثمة حلول امام العراق سوى اللجوء الى المفاوضات مع دول المنبع والاتفاق على ادارة متكاملة لمياه الحوضين (دجلة والفرات) من اجل ديمومة المياه، والمحافظة على امن واستقرار البلاد.

Authors: Subhan Fiqri , Sipahutar Ilfa Zaimi , Manalu Jhonatan , Nababan Ramsul , Sinurat Relly , Manik Sola Gracia
Published: December 2023

This research aims to explore the synergy of civic education in minimizing cyberbullying actions in the digital world. The method used is a literature review approach, employing literature study techniques and distributing questionnaires to the general public. The main findings indicate that the majority of the population, around 77%, are involved in internet usage, with 65% actively participating in social media. WhatsApp and Instagram dominate as the most widely used platforms, reaching 92.1% and 86.5%, respectively. However, the negative impact of social media, particularly in the form of cyberbullying, cannot be ignored. The impacts of cyberbullying include psychological aspects, easily traceable digital footprints, and psychosocial effects involving feelings of isolation and social rejection. The conclusion emphasizes the importance of civic education in responding to and preventing cyberbullying, not only intellectually but also socially and emotionally adept. Netiquette, or internet etiquette, takes center stage in shaping positive characters in the digital world. A holistic approach involves community-based social education, the revolution of Generation Z's character, and active community participation to minimize cyberbullying. A safe school environment is also crucial. By understanding psychosocial aspects and moral values, civic education is expected to mold a generation that contributes positively to the digital society. Therefore, understanding citizenship and digital ethics is key to creating a safe online environment and supporting the positive development of individuals and society as a whole.

A Índia de Modi: de contrapeso a potência líder?
Authors: Carrières Henri
Published: December 2023

Com a investidura de Narendra Modi no cargo de primeiroministro, em seguida à vitória eleitoral do Bharatiya Janata Party, em 2014, a Índia ingressou em uma fase particularmente assertiva de sua atuação exterior, em que busca reposicionar-se no plano internacional à luz de interesses econômicos e de segurança. Para o governo Modi, a Índia vinha desempenhando uma função de contrapeso, em vez de perseguir o papel de liderança que lhe caberia, na Ásia e no mundo. Sob essa perspectiva, tornam-se mais inteligíveis novas ênfases observadas no relacionamento da Índia com regiões e países essenciais para que se desenvolva e se legitime como potência de primeira ordem. A redefinição dos contornos da política externa indiana, ao longo destes três anos, é um processo de resultados ainda incertos, mas que tem avançado a passos rápidos e merece ser acompanhado pelo Brasil.

O processo eleitoral no Haiti, iniciado em 2015, foi objeto de sucessivos adiamentos. Após suspender por prazo indefinido o segundo turno, o Conselho Eleitoral Provisório (CEP, equivalente ao TSE no Brasil) recomendou, por suspeita de fraude, o cancelamento do primeiro turno das eleições presidenciais, realizado em outubro de 2015, e propôs novo calendário eleitoral, com a realização do 1º e 2º turnos presidenciais em outubro de 2016 e janeiro de 2017, respectivamente. Com a passagem do furacão Matthew pelo país – o pior desastre natural desde o terremoto de 2010 –, postergou-se a realização do primeiro turno das eleições para novembro de 2016. A presente cronologia reúne as principais etapas desse processo que culminou, em fevereiro de 2017, com a posse do presidenteeleito Jovenel Moïse.

The situation in the Middle East in 2017: a complex equation with numerous variables
Authors: Ait-Chaalal Amine
Published: December 2023

For decades, the Middle East is at the center stage of international relations and a matter of great concern for policy‑makers, diplomats, scholars, journalists and numerous other people interested in regional and world stability. Nowadays, more than ever, the Middle East is in turmoil. The destabilizing issues are numerous: the horrendous situation in Syria and its awful consequences, in particular the refugees’ crisis; the instability of Iraq; the deteriorating (not to say vanishing) peace process between the Israelis and the Palestinians; the delicate stability of Lebanon, that is highly affected by the Syrian war; the very shaky political landscape in Afghanistan; the complex follow-up of the 2015 Iran nuclear agreement; the war in Yemen. All those elements, and many others, are drastically affecting the Middle East, and also international peace and stability. They have consequences and after-shocks that are sometimes felt thousands of kilometers away from the Middle East. In this regard, amid this turmoil, it could be useful to try to decipher and to clarify some elements in order to understand the equation of the contemporary Middle East and the actions of the main international protagonists in the region1 . Five issues have been selected for this article: the peace process between the Israelis and the Palestinians, the situations in Syria, Iraq, and Afghanistan, and the follow-up of the 2015 Iran nuclear deal.
Os métodos de trabalho do Conselho de Segurança das Nações Unidas no pós-Guerra Fria: maior ativismo, menor transparência
Authors: Pontes Kassius
Published: December 2023

Os métodos de trabalho são, numa definição geral, o conjunto de regras que disciplinam o funcionamento do CSNU e a sua interação com atores externos, contemplando tanto normas escritas quanto um conjunto de práticas informais que se consolidou ao longo do tempo. No pós‑Guerra Fria, o crescente ativismo do CSNU teve como contrapartida uma menor transparência de seus trabalhos. O objetivo do presente artigo é examinar os três aspectos estruturais que mais contribuem para a opacidade do órgão: a ascensão das consultas informais (reuniões a portas fechadas, sem registro) como principal espaço para a tomada de decisões; o direito de veto em suas diferentes modalidades (inclusive o “veto invisível”); e o sistema de distribuição de tarefas (penholderships e presidência de órgãos subsidiários) entre membros permanentes e não permanentes. O principal obstáculo à alteração dessas três práticas é o empenho dos P5 em exercer firme controle sobre as atividades do CSNU. A despeito disso, no período recente esse colegiado tem dado passos gradativos em direção a maior abertura, com a realização de sessões de interação com atores externos em diversos formatos.
O descumprimento das resoluções do Conselho de Segurança da ONU: a tênue fronteira entre o direito brasileiro e o direito internacional
Authors: Marques Felipe , Raposo Philippe
Published: December 2023

Este artigo busca resposta para a seguinte pergunta: em quais hipóteses o direito brasileiro poderia obstar o cumprimento de resoluções do Conselho de Segurança das Nações Unidas (CSNU)? Serão analisadas três hipóteses: a negativa do Poder Judiciário nos casos de indisponibilidade de bens determinada por resolução do CSNU, com base nos direitos de ampla defesa e contraditório do acusado; a rejeição parlamentar ao envio de tropas para operações de manutenção da paz das Nações Unidas; e a declaração de inconstitucionalidade do decreto executivo que internaliza resolução do CSNU. Nesses casos, o direito brasileiro hipoteticamente obstaria o cumprimento de resoluções do CSNU, a despeito das possíveis implicações políticas e jurídicas, nos âmbitos interno e internacional, decorrentes do eventual descumprimento.

Performance Improvement of A Low Aspect Ratio Axial Flow Compressor Rotor by Means of Turbulence Generator
Authors: Sitaram N. , Thakar Ram
Published: December 2023

The present paper reports results of an experimental investigation aimed at improving the performance and operating range of an axial flow compressor using a simple passive means. A total of four configurations are tested, namely, (i) basic rotor configuration without any passive means, (ii) rotor with modified partial shroud (MPS), (iii) rotor with MPS and turbulence generator, TG, placed on the casing at the leading edge of the rotor blade and (iv) rotor with MPS and turbulence generator, TG1, placed on the casing at 44 mm upstream of the leading edge of the rotor blade. The turbulence generators are made of velcro tape. The rotor performance is determined by measuring static pressure on the casing, upstream and downstream of the rotor blade. In addition, five hole probe traverses are made at the rotor exit at five flow coefficients (at, above and below design flow coefficients). From the casing static pressure measurements, stall flow coefficient of rotor (with MPS + TG1) is found to be decreased. From the five hole probe measurements, rotor (with MPS + TG1) is found to have improved total and static pressure coefficients compared to rotor (with MPS). Slightly reduced performance of this rotor compared to the basic configuration is attributed to the adverse effects of MPS. The improved performance of the rotor (with MPS + TG1) is attributed to the energization of the casing wall boundary layer at the rotor inlet, due to vortexes generated by TG1.

Published: December 2023

Here, the elastic stability behavior of simply supported anisotropic sandwich flat panels subjected to mechanical in-plane loads is investigated using analytical approach. The formulation is based on first-order shear deformation theory and the shear correction factors employed are based on energy consideration that depends on the lay-up as well as material properties. The governing equations are obtained using the Raleigh-Ritz method assuming a combination of sine and cosine functions in the form of double Fourier series for the displacement fields. The effectiveness of the integrated formulation is tested for global characteristics considering examples related to multi-layered laminates and sandwich panels for which solutions are available.

Longitudinal Aerodynamic Parameter Estimation Using Neural Network and Gauss-Newton Method
Authors: Peyada N.K. , Ghosh A.K.
Published: December 2023

A new parameter estimation method based upon Feed Forward Neural Network is proposed. The proposed method utilizes the universal mapping capability of Feed Forward Neural Network to develop flight dynamic model of aircraft. Gauss-Newton method is used to obtain values of aerodynamic parameters by minimizing a chosen error cost function. The method has then been validated using flight data pertaining to longitudinal dynamics of aircraft. Proof of match approach has been followed to verify the estimated model by the proposed method. The results obtained using the proposed method have also been compared with those obtained using wind tunnel tests, and Filter Error method. Unlike, most of the conventional methods, the proposed method does not require a priori description of the model. It also bypasses the requirement of solving the equations of motion. This feature may have special significance in handling flight data of an unstable aircraft.
Flow Field Investigation of a Rectangular Supersonic Air-Intake With Cowl Bending
Authors: Das S. , Prasad J.K.
Published: December 2023

Experimental and computational studies are made on a rectangular mixed compression air-intake designed for Mach 2.2 to study the effect of cowl bending. Flow field details inside the intake have been captured using schlieren flow visualisation and measurement of static and total pressures. Three dimensional simulations have been made with RANS solver adopting k-ω turbulence model using FLUENT. Studies show that the configuration indicate unstart without any cowl bending whereas startup is observed with adoption of small cowl bend. In addition, improvement in quality of flow inside the intake has been observed. In general, agreements between experimental and computational results are good. Studies have been also made at different back pressures. Provision of a small cowl bending could lead to better performance of intake.

Published: December 2023

The design of complex engineered systems, such as with aerospace and automotive systems, results in a multi-discipline simulation environment that involve a high number of design subsystems and engineering disciplines as well as interactions between them. The development of novel methods and algorithms for accurately predicting the behavior physics, the increasing levels of high capability and cost effective HPC, and the availability of a broad range of independent software vendor tools are contributing towards the widespread usage of high fidelity simulation models and tools for multi-discipline analysis and optimization of product designs. The increasing usage of CFD and the complexity of associated multi-discipline simulations (analysis and design optimization) are fueling the need for balanced HPC infrastructure involving a combination of high productivity and peak performance computing, shared storage and parallel file systems for IO and data management, and advanced visualization systems, all connected by high speed networks. This paper discusses a hybrid computing architecture that optimally addresses multi-discipline CAE workloads involving high fidelity technical computing applications within a product development workflow.
Vibration Control of Fgm Thick Shells Using Higher Order Shear Deformation Theory
Authors: Narendra K. , Pradhan S.C.
Published: December 2023

Analytical solutions of Functionally Graded Material (FGM) shells with embedded magnetostrictive layers are presented in this study. These magnetostrictive layers are used for the vibration suppression of the functionally graded shells. The higher order shear deformation theory (HSDT) is employed to study the vibration suppression characteristics. The exact solution for the FGM shell with simply supported boundary conditions is based on the Navier solution procedure. Negative velocity feedback control is used. The parametric effect of the location of the magnetostrictive layers, material properties, and control parameters on the suppression effect are investigated in detail. Higher order shear deformation theory has significant influence on prediction of vibration response of thick shells. Further, it is found that (i) the shortest vibration suppression time is achieved by placing the actuating layers farthest from the neutral plane (ii) the use of thinner smart material layers leads to better vibration attenuation characteristics, and (iii) the vibration suppression time is longer for a smaller value of the feedback control coefficient.

Authors: Chand Chell Gora , Mondal Subrata , Bairagi Goutam
Published: December 2023

This paper represents nonlinear analysis of rhombic sandwich plates with orthotropic core under uniform load. Banerjee’s hypothesis [1] involving a new form of energy expression in the total potential energy of the system has been employed. As a consequence the differential equation is decoupled keeping intact its nonlinear character. The aim of the present study is to analyze the nonlinear behaviour of rhombic sandwich plates with orthotropic core under uniform load for different skew angles. The results have been obtained both for movable and immovable edges from a single cubic equation. Numerical results (central deflection vs. load) have been computed and compared with known results for square sandwich plates only. Results for different skew angles are believed to be new.
Dynamic Characteristics of MR Fluid Short Squeeze Film Damper in Terms of Reynolds Number
Authors: Jagadish H.P. , Ravikumar L.
Published: December 2023

Magnetorheological (MR) fluids are suspensions of fine micron-sized particles suspended in an appropriate carrier medium. Their rheological properties can be controlled by the application of an appropriate magnetic field and can be used in a variety of applications where damping and stiffness characteristics need to be controlled at a particular excitation frequency, based on the requirements. This cannot be accomplished with conventional fluids and thus MR fluids find application in squeeze film dampers of aircraft jet engines to provide variable damping in accordance with the magnetic field, at a particular excitation frequency. Limited information is available on the stiffness and damping characteristics of magnetorheological fluid squeeze film dampers in the literature. This paper provides information on the stiffness and damping characteristics of MR fluids used as external damping medium in Squeeze film Dampers in terms of the Reynolds number of the squeeze film. The paper calibrates the stiffness and damping characteristics of particular magnetorheological fluid squeeze film damper theoretically in terms of Reynolds number of the squeeze film for two clearance and L/D ratios operating at low eccentricity ratios, using a constant field viscosity model. The stiffness and damping characteristics are found to decrease with the increase in Reynolds number. The Reynolds number of the squeeze film is very low, highlighting the fact that the flow in the film has ceased and has solidified in accordance with the literature. The dynamic coefficients are presented in the form of empirical equations based on the theoretical investigations for different clearance, L/D ratio and eccentricity ratio, in terms of Reynolds number of the damper and enables its easy evaluation for a particular damper configuration by a mere knowledge of the Reynolds number of the squeeze film. The results assist the designer in obtaining the stiffness and damping characteristics of the squeeze film damper, based on the Reynolds number. Alternatively, the stiffness and damping characteristics of the squeeze film damper are calibrated in terms of Reynolds number for particular damper configurations. However, the research focuses on the stiffness and damping coefficients for a limited number of damper configurations under a constant excitation frequency whilst a large number of clearances, L/D ratios and excitation frequencies have not been taken into account .This research is thus intended only to showcase the method of approach by selecting finite number of damper configurations. Future work should be focused towards investigations that present the empirical equations for the entire range of clearance, L/D ratio and eccentricity ratio.

Prediction of Store Separation Characteristics Using CFD and Validation with Flight Test Results
Authors: Balachandran N. , Kumar Rakesh , Narayan D.
Published: December 2023

The design, integration and certification of a store configuration to a fighter aircraft involve extensive and expensive wind tunnel and flight testing with the objective of determining the operational and deployment envelopes for safe separation. Computational trajectory prediction techniques have shown to have the potential not only to reduce the number of flight/wind tunnel tests but also to design an intelligent test matrix. In this paper a Cartesian grid based Euler code-PARAS coupled with trajectory evaluation module (a 6-DOF time integration module) developed at ADA has been used to predict the separation trajectory of an external store from Jaguar fighter aircraft. Coupled 6-DOF Cartesian grid based methods provide reasonably accurate results with low turnaround time. A traditional multi block structured grid usually provides a better result, however handling qualities and robustness in terms of complexity of configuration and range of flight conditions makes Cartesian grid based methods an ideal choice. The current method is capable of simulating store separations without user interventions. Trajectory from the flight test has been generated using photogrammetric methods, data for which has been generated using on-board high speed camera fitted on the special POD. The computed store trajectory results are validated with flight tests and found to be in good agreement. This computational approach is further applied to predict the trajectory for higher Mach number release configurations.
