Abstract
The paper presents simulation results for the dynamics of motion, heating, and melting of porous silica particles by electro-plasma technology during production of hollow silica microspheres. With the use of available analytical and numerical solutions of equations of motion and energy for particle flow, we analyze the laws of evolution of particle parameters in the plasma flow for the case of particle diameter varying in the range D = (250-350) mm and for porosity in the range П = (0-0.6).
