Sloshing can be defined as the movement of a fluid inside a moving tank. Sloshing phenomenon is of great significance since it is involved in various fields such as propellant slosh in rockets, aircraft, cargo ships and also the trucks that carry different type of fluids. Sloshing occurs when a fluid containing body suddenly accelerates or decelerates that in turn leads to unnecessary vibrations, flammability, noise and structural failure. To reduce the sloshing effects, anti-slosh baffles are employed in the fuel tanks or any other fluid containing body. Baffles are the obstructions installed inside the fuel tank that absorb the kinetic energy of the waves and reduce the sloshing impact by lowering down the momentum of generated waves. In this research, Volume of Fluid Model has been used for Computational Fluid Dynamics analysis. After the analytical and experimental validation of the model, free surface behavior of sloshed liquid has been analyzed under different operating conditions. For experimental results, a commonly used water tank has been used to track the liquid interface under the application of an external force. Effectiveness of baffles has been studied by calculating the pressure forces on the walls of a fuel tank for both baffled and an un-baffled tank. It has been observed that baffles reduce the pressure forces to almost one tenth in the present case. Reaction forces at the tank mounts have been calculated by carrying out structural analysis of the supersonic fuel tank. Settling time is the time required for the sloshing waves to damp down and the said time for different fill levels and excitation forces has been calculated in the present research. Different cases of acceleration and fuel-fill levels have been taken to study the varying sloshing forces with time. This paper presents a detailed sloshing analysis along with a qualitative and quantitative study that is supported by analytical and experimental results.","PeriodicalId":219957,"journal":{"name":"2021 International Conference on Applied and Engineering Mathematics (ICAEM)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127535531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most significant utilization of pressuredriven actuators is related to flywheels. Utilizing actuators in blend with flywheels empowers us to control rotational speed (RPMs) and force of any instrument in a successful way. Such constructions are frequently observed in mechanical arms, boats, and marines. In this study, the design and analysis of control actuators with the flywheel are presented. One such device is a dynamometer which gives quick input estimation about the extent and power applied. Demonstrating such a framework needs a brought together way to deal with speak to the nonlinear conduct qualities. The bond diagram model is ideal for this undertaking. Moreover, traditional PID control methodology is utilized to accomplish the necessary exactness and accuracy, which is straightforward, programmed, less tedious, and proficient. Reproductions and investigations on the actuator are completed to assess the adequacy of the proposed control technique. The dynamometer framework is utilized for the testing and assessment of engine and powertrain segments. So We can utilize can dynamometer sensors to accomplish a close loop control framework as an actuator in the flywheel. flywheels accessible for when the motor driveline needs to incorporate a latency incentive to coordinate with the airframe transmission.

Landing gears are a critical structural part of an aircraft that support all up weight in static conditions and absorb kinetic energy in a form of impact loads during touch down. Complete designing along with the analysis of landing gear as per the governing principals and rules have been carried out such that it undertakes static load and impact load of the aerial vehicle having Gross Take-off Weight of 12 kg including the payload capacity of 9 kg. The work includes a comprehensive literature review, mathematical modeling of the strut, calculation of Impact force at static and dynamic conditions. Drop test dynamics has been explained thoroughly which is a prerequisite for experimental verification using drop test of the designed strut before its installation on aerial vehicle. Considering the maximum force encountered during landing, the design of the landing gear along with appropriate thickness has also been undertaken in SOLIDWORKS®. The numerical analysis of the model has been conducted using the continuum approach, considering continuous bodies. Similarly, to validate the proposed design and to determine the structural integrity of strut, finite element analysis has been carried out on landing gear assembly. The deformation, maximum stresses (Von-Mises, Principle Stress) and factor of safety have been computed using SOLIDWORKS®Simulation-Static. Moreover, three materials have been initially used, (Cold Rolled Steel, Al 7075- T6, Al 2024-T3). High strength to weight ration is a critical design consideration for any landing gear strut. The optimization parameter for the analysis is weight of the strut. Hence three optimum variants of the struts have also been proposed with 15%, 35%, 60% reduced weight of each without compromising the strength. The results indicate that the designed strut behaves efficiently meeting all the operational conditions.","PeriodicalId":219957,"journal":{"name":"2021 International Conference on Applied and Engineering Mathematics (ICAEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132965592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, transferring huge power over extensive distances using high voltage direct current (HVDC) systems is a developing and advanced technique. Although from 1950, researchers and technologists have achieved significant development in HVDC transmission systems that were based on mercury-arc valves, an important milestone was completed in the 1970s, when the thyristors switching technologies were adopted in the line commutated converter (LCC) based HVDC power transmissions. Since 1997, the evolution of power transistor-based voltage source converter (VSC) technology, and then in 2010, the modular multilevel converter (MMC) technology, opened new eras in the advanced HVDC transmission systems. With the help of pulse width modulation (PWM) based VSC, and MMC technologies, the field operators can control the real and imaginary powers, individualistically. The short length asynchronous interconnections can also be possible with these technologies. This paper will discuss the mathematical analysis of advanced HVDC transmission systems, having tie lines and power converters, and HVDC transmission for bulk solar photovoltaic (PV) power generation.","PeriodicalId":219957,"journal":{"name":"2021 International Conference on Applied and Engineering Mathematics (ICAEM)","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116603275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We focused solely on stability, emphasizing the system's rapid settling without substantial overshoots. The MATLAB state-space model is effectively developed and simulated with and without a controller. The aircraft angle, pitch rate, and pitch angle are chosen as state variables.

People are under stress due to their work, daily problems, and loss in their business. So, they use many channels and mediums to release this stress. One of the most frequently used methods is listening to music and their Holy scripts. Muslims strongly believe that their Holy book Al-Quran is the firmest way of bringing peace and pleasure in their life. Its recitation helps people relax and release the pain of patients having mental and physical sickness. To prove this scientifically, researchers evaluate the effect on the heart and brain during Holy Quran's recitation and listening. In this paper, our main focus is to analyze the activity of the heart. We are using Phonocardiogram (PCG) based heart auscultations to test the heartbeat rate before and after listening to the Holy Quran and music. PCG signals are collected from 47 subjects during three conditions, i.e., during normal, Quran, and music listening. With the help of pre-processing, segmentation, and Neural network techniques, we achieved a cumulative accuracy of 98.6%. Thus, it proves the fact that Tilawat-e-Quran brings calmness and happiness to the heart as compared to music listening.","PeriodicalId":219957,"journal":{"name":"2021 International Conference on Applied and Engineering Mathematics (ICAEM)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124544346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
