Thermo Mechanical Analysis of Divertor Test Mock-up using COMSOL Multiphysics
Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials[1]. Hence these materials are exposed to the ... En savoir plus
Modelling of Pressure Profiles in a High Pressure Chamber using COMSOL Multiphysics
High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started ... En savoir plus
Diffusion Modeling in TGA in Context of CO2 Gasification of Char
The Thermo- Gravimetric Apparatus (TGA) is often used for kinetics determination. In TGA setup, gasification reaction may be limited by the reach (diffusion) of the gasification agent to the internal surfaces of the char particles. In addition to this, after some time, ash is formed ... En savoir plus
µHeater on a Buckled Cantilever Plate for Gas Sensor Applications
In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design ... En savoir plus
