Abstract

A numerical code was developed to investigate the characteristics of drag and heat reduction by the lateral jet in supersonic flows, the Reynolds-average Navier-Stokes (RANS) equations was solved by using high resolution upwind scheme AUSMPW+, three order MUSCL reconstruction method and k- SST turbulence model with solving the unsteady heat transfer equations. The code was validated by an experimental case. The computed results indicate that: the numerical code can effectively capture the flow features, and the pressure and Stanton number on blunt body surface are significantly decreased with the addition of the lateral jet. The lateral jet was proved to be an effective method to reduce drag and heat.
