Experimental and Computational Modeling of the Processes of Supersonic Outflow from a Half-Closed Channel

This article is devoted to the investigation of the thermo-gas-dynamic processes in half-closed channels, into which air is fed through holes focused on the axis. We have investigated the influence of the size of holes, their arrangement, and the orientation of jets fl owing out through them, as well as of the settling chamber pressure on the pressure at various points of the channel wall and on the fields of flow parameters (the field of Mach numbers and the pressure and temperature fields). Experimental investigations were accompanied by numerical 2D and 3D calculations.
