Transonic Potential Flow Computation about Three-Dimensional Inlets, Ducts, and Bodies

Abstract

An analysis has been developed t o predict transonic potential flow about three-dimensional objects including inlet, duct and body geometries. Finite-differences and line relaxation are used t o solve the complete potential flow equation. The coordinate system is independent of body geometry and hence places n o restrictions on body shape. Cylindrical coordinates have been used for the computer code. The analysis has been programmed for the Control Data Corporation CYBER 203 vector computer with this programming oriented t o take advantage of the vector processing capabilities of the computer. Comparisons of c o m p ~ ~ t e d results with experimental measurements are presented to verify the analysis.
