Numerical simulation of a supsersonic base bleed projectile with improved turbulence modelling

摘要

This paper deals with Navier-Stokes simulations employing Chien's (1982) k-epsilon turbulence model for the flow past a supersonic projectile with base bleed. ^A new way of avoiding turbulence-related problems near stagnation points is suggested and results of simulations with and without the modification are presented. ^The theoretical background of the modification is briefly described. ^(Author)
