Abstract

Numerical simulation was conducted to obtain the temperature and gas flow fields in inductively coupled thermal plasma (ICTP). Influence of gas composition, power supply, quenching gas, carrier gas, pressure and frequencies were investigated on thermal plasma temperature fields. Results indicated that higher oxygen fraction in gas composition makes the shrinkage of the thermal plasmas, which increases power density in local volume. Further, an increase in the quenching gas, the carrier gas and the pressure did not affect the temperature of thermal plasma. On the other hand, the temperature in thermal plasma decreased at axial position along with degradation of frequency.
