Abstract

Numerical simulations of the trajectory and thermal history of spherical particles injected into inductively coupled plasma torches working at atmospheric pressure have been performed taking into account the effects of coupling between particles and plasma and the turbulent dispersion of the particles, in the frame of a stochastic approach. The computational domain includes the torch region, as well as a region downstream the torch representing a reaction chamber.
