Numerical Simulation of Thermal and Flow Characteristics Inside a Rod Type Cathode (RTC) Plasma Torch
Keyword(s):
A mathematical modeling of argon thermal plasma flows inside a rod type cathode (RTC) plasma torch based on electromagnetic principle is presented. Numerical investigations on the model are carried out for a better understanding of its output characteristics in terms of the plasma velocity, temperature, mass fraction and electro-magnetic field calculations. A direct comparison of the present numerical results with a reported experimental data is made and found to be in fair agreement.
