Abstract : An analytical model has been formulated and a computer program has been developed to compute the transonic flow field in either two-dimensional or annular axisymmetric nozzles. The analytical model assumes the inviscid, irrotational flow of a perfect gas, and is based on a Taylor series expansion around a Mach number of unity. An expansion parameter, epsilon is defined in terms of the wall geometry at the minimum area cross section. The method is capable of treating unsymmetric wall geometries. First, second, or third order solutions can be obtained from the computer program. (Modified author abstract)
