Abstract

The three dimensional crossing shock waveturbulent boundary layer interaction caused by an asymmetric 70 x 110 double fin was calculated by solving the Reynolds averaged Navier-Stokes equations with a full Reynolds Stress Equation turbulence model. An implicit approximate factorization method is used for the temporal integration. Roe’s scheme is used for evaluation of the convective terms of the mean flow and Reynolds stress equations with a third order MUSCL-type differencing. The computed surface pressure is in good agreement with the experiment. The computed heat transfer coefficient shows a modest improvement compared with the previous results obtained using the k – ε model with Chien's low Reynolds number correction. Both computations of the heat transfer display significant deviations form the experiment. The tests of the grid refinement, different upstream boundary layer profiles and different isothermal wall temperature axe also presented.
