Choking and mixing of two compressible fluid streams
Abstract
The mixing of a supersonic with a subsonic stream is treated in a onedimensional, ideal gas analysis to determine when the mixed flow can be supersonic and to reveal the relationship between certain phenomena described by the terms 'forbidden region' or 'thermal choking'. A singularity in the equations is shown to divide the mixing process solution curves into two branches: subcritical or supercritical leading, respectively, to subsonic or supersonic mixed states.
