Incorporation of Boundary Layer Heating Predictive Methodology into NSWCDD Aeroprediction Code.

摘要

Methods have been incorporated into the Naval Surface Warfare Center, Dahlgren Division aeroprediction code to permit the computation of heat transfer rates and recovery temperatures as part of the high Mach number solution. A mass balance technique has been included to determine the correct boundary layer edge entropy to use along the surface of blunt bodies. Refinements were also made to the pressure prediction routines to remove discontinuities and improve overall results. Comparisons of results from the new methods with those from more advanced engineering codes, with other techniques of similar technical level of detail, and with experimental data show good agreement. These new capabilities make possible the rapid computation of three-dimensional heat transfer information for a wide range of geometric configurations and flight conditions....
