Computational Fluid Dynamics Simulation of Turbulent Waverider Flowfield with Sideslip

Abstract

To better understand the waverider hypersonic flowfield with sideslip, the flowfield computational fluid dynamics simulation for a selected waverider at 5-deg angle of sideslip off-design condition is conducted. The off-design flow field is more complicated than the nominal design, inasmuch as there is very strong shock-wave/boundary-layer interaction at the windward waverider tip, and a detached shock at the leeward tip, whether the flow conditions are inviscid or viscous. For these different simulations, the pressure coefficient distribution basically has the same values except near the tip, but the shock attachment point on the lower surface and force coefficient value are different. The shock-wave/boundary-layer interaction and shock attachment pattern at the windward tip strongly affect the waverider pressure and local skin-friction coefficient distribution in that region. The simulated pressure coefficient distribution is in good agreement with available experimental results.
