Chemical Reaction Considered Numerical Simulation on Preparation of AlN Nano Powder by Non-transferred Thermal Plasma

Numerical simulation on the thermal plasma characteristics was carried out inside of the DC non-transferred thermal plasma system to preparation of AlN nano powder. Especially, chemical reactions were considered between thermal plasma, Al metal bulk, and NH3 gas inside of the reactor by FLUENT computational fluid dynamics code. In our simulations, 2-D axis-symmetric domain was assumed, and the DPM (discrete phase model) model was used for investigating the chemical reaction of AlN which is synthesized from evaporated Al metal and NH3 gas.
