Computation of an Axisymmetric Nozzle Flow

摘要

In this paper we compute the axisvmmetric. inviscid, compressible, steady flow from a nozzle. The Legendre, or contact, potential formulation is used in the hodograph plane. We have emphasized the axisymmetric case because the hodograph equation is then nonlinear, whereas it is linear for the more often studied two-dimensional flow. Results and formulation are compared and contrasted with those of earlier work by Alder [1]. The ultimate goals are to gain insight and provide a workable framework for dealing with axisymmetric flows that exhibit transonic behavior.
