Abstract:

This report covers the Phase II progress in a two-phase effort to develop the full-potential finite-volume algorithm for transonic flow over wing-body configurations. The work included investigations of grid-generation schemes, extension of the wing-body code to more complex configurations, and the effects of vortex wake modeling. The wing-body code was used to analyze a computer-designed military aircraft wing which had been wind tunnel tested. Computed results agree quite well with the experimental data. A second test case was also run for a business jet aircraft. Unfortunately, experimental data for the test case were not available for comparison. Author
