Abstract

The opposing jet is proposed for aerodynamic heat reduction. In this study, the opposing jet has been applied for three nose configurations, including ogive body, blunt body and ogive body with extended nozzle, to investigate the efficient nose configuration for the opposing jet. Numerical study has been implemented for the supersonic flow at M = 3.98 and the results showed that there is a direct correlation between the applied nose configuration and the effect of the opposing jet. Detail flow field analysis revealed that to avoid constructing the strong recompressed shock is important and essential to reduce the aerodynamic heating by using the opposing jet. Of all three nose configurations, it was found that the ogive body with extended nozzle is the most effective model as for reduction of aerodynamic heat because significant heat flux reduction was acquired with smaller mass flow rate jet compared to other nose configuration.
