The interaction of two streams of compressible fluid directed at an angle to one another i examined. The main stream of gas is compressed by an active stream which is supplied through an annular slit located in the region of minimum cross section of the main stream. Ratios of aerodynamic compression are derived for two cases, a convergent channel and a Laval nozzle. The difference between these two cases is that in a divergent channel the separation zone is in communication with the atmosphere, and in a Laval nozzle it is a closed region. This gives unique conditions for solution of the problem.
