Gas-dynamic and thermal characteristics of the gas flow in the flow part of a small-scale plasma-chemical reactor for trichlorbiphenyl decomposition were calculated numerically. The investigations were performed with no regard to the chemical interaction of the components: in the calculations, the treated substance was replaced by a simulator (water steam), water steam was also used as an oxidant. Mathematical model of the flow is based on the complete system of Navier - Stokes equations in the context of axisymmetric task statement, with due regard to the gas flow swirling. The calculation results enabled us to choose the optimum geometrical parameters of the reactor design.
