Abstract:

Simple approximate analytical relations are given for the duct contours for the flow of an inviscid compressible gas through a special class of plane and cylindrical supersonic side inlets and exits for which the internal flow is isentropic or nearly isentropic. The ducts treated are formed by joining a reverse or forward PrandtlMeyer flow region to a radial sink or source flow by means of a transition region. For this special class of ducts, a greater degree of freedom is achieved in the choice of certain duct dimensions than is possible by the more obvious method of selecting a pair of streamlines from the flow in a wind-tunnel nozzle or a contoured rocket-exhaust nozzle designed by one of the many methods available in the literature. In the case of cylindrical ducts, the increased freedom in the selection of some of the duct dimensions is accomplished at a sacrifice in the allowable duct height as a consequence of an approximation made in the analysis.
