Cone-Derived Waverider Flowfield Simulation Including Turbulence and Off-Design Conditions
Using the numerical scheme of Roe's flux-difference splitting, the Baldwin-Lomax algebraic turbulent model,and the time-averaged thin-layer Navier-Stokes equation, the flowfields for a selected Rasmussen's waveriderforebody are investigated. Specific cases include turbulent flow on-design condition (M^ = 4, a = 0), turbulent flowoff-design condition (Moo = 4, a = 5 deg), and laminar (and Euler) flow off-design condition (M^ = 5, a = 0). Forcomparison purposes, some results previously reported by the authors are presented. The off-design flowfields aremore complicated than the on-design ones. For the M^ = 5 waverider, there is very strong stock-wave/boundary-layer interaction. For the a = 5 deg waverider, there is a detached shock, resulting in a small separation bubble anda vortex on the upper surface. The shock-wave/boundary-layer interaction and shock attachment pattern stronglyaffect the waverider pressure and local skin-friction coefficient distributions.
