Wireless power transfer is an emerging technology with many potential applications. This technology may be of particular value when remotely controlled in extreme physical conditions. This study explores the ability of the COMSOL software to predict the performance of thermal management systems coupled with a commercially available wireless power amplifier. This study has undertaken the task ...

We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a double Wheatstone-bridge. In operation, each bridge is supplied by a constant current and the self-heating of ...

The predictive engineering of materials is matured from predicting properties from known morphology or constituents to engineering novel morphology for superior properties. The focus of this paper is about implementation of computational material mechanics modeling method in COMSOL Multiphysics software for engineering the constituents for superior properties. A brief review of property ...

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground cavities. In order to accurately perform these multiphysics modelings at high space and time scales, it is ...

Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. The usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. This ...

Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible element will be a ceramic beam with a Weathstone bridge on its surface. A structural analysis on the case has been ...

We present a novel multi-layered electrode fabrication technique for polymer electrolyte membrane fuel cells (PEMFCs). This method consists of alternate layers of Pt deposition (0.05 mg/cm²) by sputtering on the painted multi-walled carbon-Nafion layer (CNL) with larger concentration of catalyst particles closer to the membrane. Parametric models were developed and validated by experimental ...

Oxygen-free methane aromatization has been attracting growing attention due to a potential means for producing high valuable products such as aromatics and hydrogen. Many studies have been focused on catalysts screening and characterization, and elementary thermodynamic steps of the reaction. However, little attention has been paid to fluid dynamics which are important for an industrial ...

The possibility to detect and probe molecules in microfluidic devices gives rise to interesting applications. There are different approaches how to detect and probe particles, but a common step, for most methods, is to place the particles on a sensor. This can be done by applying external field gradients, or in this case by utilizing gravitational and hydrodynamic effects. Therefore, the sensor ...
