INVESTIGATION OF FLUX FORMULAS IN TRANSONIC SHOCK-WAVE TURBULENT BOUNDARY-LAYER INTERACTION

The aim of the present study is to examine the accuracy and improvemen t of various numerical methods in the solution of the transonic shock/ turbulent boundary layer interaction problem and to show that a signif icant source of numerical inaccuracies in turbulent flows is not only the inadequacy of the turbulence model but also the numerical discreti zation. Comparisons between a Riemann solver and a flux-vector-splitti ng method as well as between various numerical high-order extrapolatio n schemes with corresponding experimental results are presented.
