摘要

This paper describes a computational parametric study showing how the preceding heat release position affects aerodynamic characteristics of a hemisphere in a hypersonic flow. A thermal and chemical nonequilibrium viscous flow is assumed. For this purpose, finite-rate chemical reactions with seven species are considered to treat chemical non-equilibrium. Park's two temperature model is used to take account of thermal non-equilibrium. Results show that an increase in the distance between heat release and hemisphere causes both the drag and the amount of heating rate to decrease monotonically. These reductions saturate when the distance becomes longer than 14 times the radius of the hemisphere.
