Radiofrequency ablation is a minimally invasive techinique which is used to treat some kinds of cancer. The realism of theoretical models is very important. An influential factor in this realism is mathematical functions that model the temperature-dependence of tissue thermal and ... En savoir plus
This is an preliminary attempt to simulate the complicated tunnel induction furnace, used for the heating of the long wire moving at a certain speed to achieve the desired mechanical properties. The furnace consists of 108 numbers of turns, with embedded cooling channel inside to cool ... En savoir plus
Vacuum distillation furnaces (VDFs) are employed for purification and consolidation of heavy metals from their dendritic forms which are entrained with molten salts. The VDF is an induction heated furnace which is operated at a temperature of 700-1400 °C and at a pressure of 0.01-600 ... En savoir plus
This paper presents the simulation of exhaust gas heat recovery system for an automobile using COMSOL Multiphysics®. A double pipe heat exchanger is modeled in which the tube side medium is the hot exhaust gas and the shell side medium is water. The problem is divided into three parts i ... En savoir plus
High-power couplers working at 350 MHz for particle accelerator cavities are presently under development in the LEHIPA project at BARC. It is important to analyze RF losses on conducting surfaces and resulting thermal profiles. COMSOL Multiphysics® is used to study these coupled RF ... En savoir plus
This paper deals with an integrated numerical and experimental analysis work aiming at the investigation of the thermal stress on nanowires in electronic gadgets especially computers and mobile phones. The comparative study of the nanowires are analyzed through the Thermal Stress physics ... En savoir plus
The Helicon-Injected Inertial Plasma Electrostatic Rocket (HIIPER) is a two-stage electric propulsion system comprising of a helicon plasma source and an inertial electrostatic confinement (IEC) device for plasma production and acceleration, respectively. Several diagnostics such as a ... En savoir plus
The production of polymer fibers is done by drawing raw material (preform) in a vertical cylindrical furnace whose heated walls radiantly heat the preform. The wall temperatures are very high and the dominant heat transfer to the fiber is by radiation with little effect from the ... En savoir plus
Electro refining is one of the important step in the Pyro processing nuclear spent fuel with molten salt. The electro refiner is a process vessel consists of anode ,cathodes and stirrers and ultra –high pure argon gas is provided at the top for inert atmosphere and at the bottom a ... En savoir plus
Shielded transportation casks are commonly used for transportation and storage of radioactive waste materials. Design approval of such casks by regulatory authority is subject to its compliance with a thermal test (among other tests) Due to exposure of cask to fire , there is a ... En savoir plus
