Modern gas turbine systems for power generation are prone develop so-called thermosacoustic instabilities in the combustion chamber. Physically, these instabilities emerge as large amplitude pressure oscillations within the combustor, which are caused by constructive feedback ... Read More
Dr. Shekhawat is currently the General Manager for New Products Development at Secure Meters Ltd., Udaipur. Prior to this, he was with CEERI, Pilani for 23 years. He has a Ph.D., MS, M. Sc. (Physics) and BE (EEE) from BITS, Pilani. He is the recipient of several honours including the ... Read More
Logging-while-drilling (LWD) acoustic transducers provide real-time data about the geologic and geophysical properties of the borehole that ensure safety margins and optimize completion. It is important to understand what causes the different resonance modes in the transmitter and obtain ... Read More
GalFeNol is a new Giant Magnetostrictive Material that can be used in energy harvesting especially in vibration reduction applications, thanks to the Joule and Villari effects. A 3D-model of GalFeNol rod is stressed by a time varying longitudinal force of 1000 N. The study has been ... Read More
Modern gas turbines suffer of the phenomenon of combustion instability, also known as “humming”. The main origin of the instability is considered to be related to the interaction between acoustic waves and fluctuations of the heat released by the flame. This paper presents a ... Read More
A piezoelectric transformer allows purely mechanical transfer and scaling of electrical energy via simultaneous utilization of both the direct and converse piezoelectric effects. This mechanical energy transfer enables a wide range of functional differences from typical magnetic-based ... Read More
The influences of curvature effects and swirl intensities for Non-Newtonian viscous fluid flow in a curved tube have been numerically investigated by using COMSOL Multiphysics®. The twisted tape, which are located directly in front of the curved part, are used as swirl flow generators. ... Read More
VRALA is the ideal candidate as an Adaptive Optics actuator at visible wavelengths. Its electric characteristics variations, suitable current commands, and an effective magnetic circuit geometry provide a 2 kHz correction bandwidth and a 25 mm actuator density. The magnetic core allows ... Read More
The overall goal of this work is the use of COMSOL Multiphysics® in the modeling of the current density distributions for the electrodeposition of aluminum coatings from ionic liquids. The local current distribution is strongly dependant on the conductivity and on the geometry of the ... Read More
In this work COMSOL is utilized to obtain the Mason lumped parameter model for a piezoelectric transformer (PT) design. The Mason lumped parameters are relevant in the design process of power converters. The magnitude of the impedance is simulated for a specific interleaved multilayer ... Read More
