Abstract:

A recently reported Parabolized Navier-Stokes code has been employed to compute the supersonic flow field surrounding an ogive-cylinder-boattail body at incidence. The computations were performed for flow conditions where an extensive series of experimental surface pressure and turbulent boundary-layer profile measurements had been obtained. Comparison between the computational results and experimental measurements for angles of attack up to 6 deg. show excellent agreement. At angles greater than 6 deg. discrepancies are observed which are tentatively attributed to three-dimensional turbulence modeling errors.
