Semielliptic computation of axisymmetric transonic flows
Abstract
A numerical solution algorithm for the computation of axisymmetric, transonic duct flows is presented. The algorithm, which solves steadystate equations for the primitive variables, is based on a specially derived pressurecorrection equation expressing a kinematic compatibility condition. After being derived, the algorithm is used to predict the flow field inside an annular convergentdivergent nozzle that features exceptionally small radii of curvature for the walls at the throat section. The algorithm is economical with regard to both storage and computational time requirements.
