Development of mathematical modeling tools designed
for calculations of supersonic flows in aerodynamic windows of gas lasers
is considered. Numerical simulation of steady-state supersonic flows of an ideal
compressible gas in curvilinear channels and nozzles with various pressure differences
is performed on the basis of a finite volume method and a marching scheme. Flow
patterns in supersonic jets observed with the uniform velocity distribution
and a free vortex velocity distribution on the nozzle outlet section are compared.
Channel designing tools are developed based on the solutions of a sequence
of direct problems. The numerical results show a high efficiency of the software
developed for problems related to the channel profiling and to the control
of steady-state supersonic jet flows.
