Induction furnaces are employed for vacuum distillation process to recover heavy metals after electro-refining operation. Induction furnace of suitable heating rate and cooled by passive means are required to be developed for this purpose. It is planned to set up a mock up induction furnace which will simulate the conditions to be realized in actual vacuum distillation furnace for this purpose. ...

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in planning their thermal treatment doses. This will maximize therapeutic effects while minimizing side effects. ...

Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). PAW has been unnoticed because it is more complex and requires more expensive equipment compared to other ...

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the influence of a steady magnetic field on partial penetration keyhole laser beam welding of aluminum. Three-dimensional ...

Micro-Heaters are the key components in sub-miniature micro-sensors, especially in gas sensors. The metal oxide gas sensors utilize the properties of surface adsorption to detect changes in resistance as a function of varying concentration of different gases . To detect the resistive changes, the heater temperature must be in the requisite temperature range over the heater area. Hence the ...

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon complex melting and solidification phenomena happening due to interaction of high-intensity laser with the ...

The simulation of heat and moisture transfer represents an essential resource in designing energy efficient buildings. In this paper a time-dependent wall model, consisting of several homogeneous domains, with third-type boundary conditions imposed on the surfaces, is implemented in the COMSOL Multiphysics environment. Temperature and moisture content is calculated inside the construction for ...

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map the tab to establish its thermal mapping. This led us to perform simulations at each ASIC of the tab that ...

Thermoelectric power generation has been envisioned as a clean energy alternative to conventional thermal to electric power generation for decades due to its noiseless and low-cost operation. However, a typical thermoelectric generator suffers from low device efficiency, so it has been a constant endeavor for thermoelectric researchers’ community to consider alternate thermoelectric materials ...
