Abstract
Mechanisms are analyzed of interaction between a laminar gas flow (velocity of flow of molecular gas of up to 10 m/s) and a high-pressure (of the order of atmospheric pressure) contracted electrodeless plasma formation. The solution of a set of equations of motion and energy balance (with specific energy input of up to 3 J/cm3) for a weakly compressible gas is used to obtain the profiles of components of velocities and temperature of gas flow. It is demonstrated that the plasma formation (exhibiting a transverse dimension of up to 6 mm and longitudinal dimension of up to 30 mm) affects significantly the formation of the field of velocities of flowing gas. The preferred mechanism of heat transfer in the direction of the axis of flow is by forced convection. The rate of radial transfer of energy to periphery is defined by thermal conductivity. Experimental results are given of axial distribution of temperatures for a given plasma formation in the air, which are in adequate agreement with experiment.
