Abstract

One of the main difficulties in modelling thermal plasma flows is the interaction between turbulence and reacting phenomena. In the less difficult case where both plasma and diluting flow are produced with the same gas, a validation study of a numerical modelling has been done. This validation study consists in incompressible flow situations, non-reacting flows with large density differences, and thermal plasma flows mixing with cold flow. In the case of plasma chemical reactors, the paper discusses some aspects of the problem of interaction between turbulence and chemical reactions.
