Viscous Effects in Low-Density Nozzle Flows

Abstract

Viscous effects in low-density nozzle flows were investigated numerically, and comparisons were made with experimental data. The numerical method of Patankar and Spalding was modified to solve the internal laminar boundary-layer equations for two-dimensional flow or axisymmetric flow with or without transverse curvature. A listing is given of the computer code. Boundary-layer displacement thicknesses for typical nozzle geometries and flow conditions are presented. Solutions were obtained for specific conditions corresponding to experimental data. The result is a relatively fast, simple to use numerical procedure, which is shown to give results in good agreement with experimental data.
