Abstract
RESULTS of numerical analyses of three-dimensi onal, nonequilibrium, viscous shock-layer flows over complex geometries are presented in this paper.1 The viscous shocklayer code (VSLNEQ)2 for analyzing nonequilibrium, multicomponent, ionizing airflow over sphere-cones has been extended to analyze multiconic geometries. The geometries considered for the analysis include straight and bent biconics and a sphere-cone-cy linder-flare with a moderate flare angle. This code is capable of analyzing shock-slip or no-shock-slip boundary conditions and fully catalytic or noncatalytic wall boundary conditions. The results from the nonequilibrium code have been compared with perfect gas and equilibrium air results. In general, the surface pressure distributions are in good agreement, whereas the nonequilibrium heat transfer is about 15% higher than the perfect-gas results. The aerodynamic forces and moments at the base of the bent biconic for various flow conditions are presented and they agree reasonably well with each other.
