Abstract
The supersonic base flow of a blunted cone-cylinder rocket model in the presence of a central propulsive jet is investigated numerically by solving three-dimensional Reynolds averaged Navier—Stokes equations in an unstructured mesh using a commercial computational fluid dynamics software. The effect of the computational grid and the turbulence model in predicting the radial variation of base pressure has been brought out. Very fine grid ( y+∼ 2) is required to correctly predict the base pressure. The renormalized group k—ɛ turbulence model performs better compared to the k—ω turbulence model in predicting the base pressure. It was observed that the base flow characteristics in the lower and upper portions of the base are significantly different due to the influence of model support.
