Status Report on the Calculation of Blunt Body Flow Fields in Supersonic, Nonuniform Flows
Abstract
It is difficult to eliminate flow nonuniformities in facilities for the testing of ablative heat shield materials. To investigate the potential effects of free-stream nonuniformities, a modification of an existing analytical method developed by Moretti and co-workers for uniform blunt body flows has been used. The results of the study indicate that for the flow model used, the free- stream nonuniformity can significantly alter the flow properties of the body surface. In particular, free-stream Mach number gradients can result in velocity gradients at the body surface which, in turn, will influence local heating rates.
