Parametric study of the effect of exothermic coating properties on blunt nose drag reduction in hypersonic flights

摘要

The most recent idea of using the exothermic coating to reduce the drag coefficient on blunt noses in hypersonic flows is numerically simulated to study parametrically the effect of material properties. The conjugate heat transfer is considered by simultaneous solution of flow and solid phase governing equations in numerical procedure. The results show that changing some effective parameters in material properties may increase the coating effectiveness significantly. Using such analysis leads to choose the proper materials for specific flight missions.
