Computations of the Magnus Effect for Slender Bodies in Supersonic Flow

摘要

A recently reported Parabolized Navier-Stokes code has been employed to compute the supersonic flow field about spinning cone, ogive-cylinder, and boattailed bodies of revolution at moderate incidence. The computations were performed for flow conditions where extensive measurements for wall pressure, boundary-layer velocity profiles and Magnus force had been obtained. Comparisons between the computational results and experiment indicate excellent agreement for angles of attack up to 6 deg. The comparisons for Magnus effects show that the code accurately predicts the effects of body shape and Mach number for the selected models for the selected models for 2 < or = M < or = 4. (Author)
