Аннотация:Stagnation pressure is usually increased by so-called machine methods—various compressors that operate by supplying mechanical energy to the flow. This paper considers a method for increasing the stagnation pressure based on the thermal influence on the flow (heat removal). The influence of various factors on the degree of the increase in stagnation pressure for a channel flow under only thermal influence is studied. This paper considers various flow cooling methods. It is shown that evaporative cooling is the most effective in terms of increasing the stagnation pressure. A review of publications on the use of evaporative cooling to increase stagnation pressure is provided. Based on a one-dimensional model of an evaporative cooling device, it is shown that it is possible to increase stagnation pressure by a factor of 1.25 at supersonic inlet velocities.
