A Piezoelectric Directional Microphone is demonstrated based on a bio-mimetic design inspired by the parasitoid fly Ormia ochracea using the PiezoMUMPs multi-user foundry. The device simulation was conducted using COMSOL Multiphysics® software which achieves a directional sound field ... En savoir plus
The development in metamaterial science and technology has created many exhilarating applications from microwave to optical frequency region in which invisibility cloaking is one of the exciting application. In recent years, the RCS reduction characteristics through cloaking structures ... En savoir plus
SOFC is a high temperature electrochemical device known for its fuel flexibility. Apart from using pure hydrogen, it can utilize CO (carbon monoxide), CH4 (methane) or any other higher hydrocarbon. Since methane is highly researched hydrocarbon fuel, it was chosen to start with. The most ... En savoir plus
COMSOL Multiphysics® software is used to explore the impact of distributor width on the film thickness, and the resulting sensitivity of overall thermal efficiency in a plate and frame triple-effect evaporator. A stable film is crucial to maintain a minimum wetting rate, to circumvent ... En savoir plus
Reaction-Diffusion equation is simulated for heterogeneous catalytic reaction involving a porous catalyst particle surrounded by liquid reactants. COMSOL Multiphysics® software along with transport of dilute species module is used for this purpose. Global Variables such as reaction ... En savoir plus
This paper presents the design and analysis of a high power radial flux Brushless DC motor for electro-mechanical actuation system. The motor is used for driving an electro-mechanical actuator of 20 ton capacity. Surface mounted, radially magnetized permanent magnet design is mostly ... En savoir plus
Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of ...

COMSOL Multiphysics® software was used to model radial source flow in two dimensional homogeneous porous media. Two-Phase Darcy's Law (tpdl) is used to model miscible viscous fingering. Fingering patterns obtained on using different mesh are discussed. Evolution from 'flowers' to ... En savoir plus
A three-dimensional heterogeneous model of breast has been modeled with a spherical tumor of 1.5 cm. PID controller has been used to perform temperature-controlled RFA of breast tumor. The coupled effect of blood perfusion and variable conductivity during RFA has been investigated. The ... En savoir plus
Piezo buzzers, made of piezoelectric material glued on a brass plate, are usually used as signaler, but the buzzer can also be used to convert mechanical into electrical energy. If acceleration influences the buzzer, the structure is bent by its mass and a voltage can be measured between ... En savoir plus
