The well known Pierce design of electron and ion diodes is the base of particle source extraction systems [1,2]. It was heavily studied up to 1960 with analog computing and it now offers us a known case against which to compare the precision of fluid and particle tracing codes. The ideal ... Read More
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 ... Read More
Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... Read More
In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... Read More
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...

The present research work aims to present thermal analysis of Electrical Discharge machining. During its machining process a large amount of heat is generated due to sparking phenomena, It has been assumed that heat distribution follows the Gaussian Distribution function. As such a ... Read More
Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing ... Read More
High power Terahertz (THz) sources have become a topic of great interest for a wide variety of applications from medical science to security systems and from material science to telecommunication. The high output power of these THz sources mainly depends upon high current density and ... Read More
