Transonic Flow Calculations for a Wing in a Wind Tunnel

A computer program has been developed to calculate inviscid transonic flow over a swept wing in a wind tunnel with constant rectangular cross sections and with specified normal or tangential flow at the walls. An approximately orthogonal computational grid that conforms to the wing and the tunnel walls was developed for application of the Jameson-Caughey finite-volume algorithm. The code solves the full potential equations in fully conservative form using line relaxation. Sample calculations show the effect of tunnel walls. Comparisons with experimental and other theoretical results are presented.
