Mathematical simulation of coal particles combustion

Abstract

In this paper example of mathematical modeling of mixture coal ignition using plasm jet is presented. At the beginning the computation was simplified so that coal mixture is ignited by air about 5700 K instead of plasm. Task is defined as turbulent flow of air and coal particles with heat transfer and chemical reaction. In software Fluent 6.3 flow can be solved by turbulent models, heat transfer then by radiation models. Mathematical model of continuous discrete phase was created, which characterizes adrift of coal particle. Model was solved by method of finite volume.
