A Numerical Investigation of Supersonic Flow Around Aft Bodies

Abstract

A numerical investigation has been made for supersonic flow past a cylindrical aft body with and without base bleed and a cylindrical boat tail. Comparison was made to available experimental data. The effect of grid cell density and turbulence models were examined. The calculation of the base flow region was much more highly dependent on grid density that was the forebody or outer flow field Agreement between the numerical and experimental results improved with the inclusion of the base bleed.
