Characteristics of flow of oscillatoryrelaxing gas in nozzles with constant crosssections in throat region
Abstract
A steady twodimensional mixed sub and supersonic flow of a nonviscous nonheatconducting oscillatoryrelaxing gas in flat compressionexpansion nozzles having an area with a fixed cross section in the throat area and two bends in the contour at the beginning and end of the fixed area was investigated. The results were obtained by solving gas dynamic equations and relaxation kinetic equations simultaneously based on the approach used for the direct problem of the flow of gas in a Laval nozzle in the presence of nonequilibrium physicochemical processes. When 1 sub p 2(1 sub p = L sub p/(h*/2), where L sub p is the length of the area with fixedcross section of diameter h* in the throat region, all of the oscillatory energy stored in the subsonic part of the nozzle is lost.
