SUPERSONIC FLOWS IN CHANNELS AND JETS WHEN APPLIED TO THE PROBLEMS OF DESIGNING AERODYNAMIC WINDOWS OF GAS LASERS

摘要

Consideration is given to issues associated with the development of aids for mathematical modeling of steady-state supersonic perfect compressible gas flows in aerodynamic windows of gas lasers. A comparison is made of flow patterns in supersonic jets, which appear when a uniform velocity distribution and a velocity distribution corresponding to the free vortex are realized on the nozzle section. Aids for designing channels are developed on the basis of solution of a sequence of primal problems. The calculation results show the high efficiency of the developed software as applied to solution of problems associated with the contouring of channels and nozzles and with the control over supersonic jet flows.
