TRANSONIC FLOW IN TWO-DIMENSIONAL AND AXIALLY-SYMMETRIC NOZZLES

Abstract

By means of suitable expansions in inverse powers of R, the radius of curvature of the nozzle profile at the throat measured in throat half-heights, the velocity components in the throat region of a convergent-divergent nozzle can be calculated. The first three terms of the series solution have been obtained both for two-dimensional and for axially-symmetrie nozzles. The numerical accuracy of the solution is confirmed by comparison with the known exact solution along the branchline.
