Abstract
The present study shows that enhancement of mixing efficiency (increasing the total pressure of the mixture) requires expansion of the cross section of the high-pressure gas flow. It is found that the parameters of the mixtures are identical in the cases of distributed and one-step mixing of the perfect gas flows. However, distributed mixing (multistep mixing as a finite-dimensional analog) is more reasonable because it ensures flow control to provide conditions to satisfy the existence of a steady flow in the channel.
