Thermal Plasma Effect on Ceramic Microsphere Formation. Part 1. Heating and Evaporation
Abstract
The paper considers the process of heat transfer between thermal plasma and agglomerated SiO2 particle. The dispersion boundaries of particles entering the thermal plasma flow are calculated in the paper. The experiment parameters include 3500 K temperature, 1-2×106 W/m2 specific heat flow, and 122 m/s flow velocity. The effect of the initial particle porosity on the dynamics of heating and evaporation during their motion in plasma flow is described. The model of the concentration liquid phase containing in particle with allowance for the actual chemical composition is proposed taking into account calculations of heating and evaporation dynamics of agglomerated particles in thermal plasma flow.
