摘要: Abstract : An investigation of the accuracy high-order methods for hypersonic shock wave turbulent boundary layer interaction (SWTBLI) is presented. The numerical considered here comprise Monotone-Upstream Central Scheme Conservation Laws (MUSCL) and Weighted Essentially Non-Oscillatory (WENO) schemes, 2nd to 9th order accurate in conjunction with structured mixed element unstructured grids. Both Implicit Large Eddy Simulation (ILES) Reynolds Averaged Navier-Stokes (RANS) computations have been performed. effects discretization on turbulence transport equation, including approximation method viscous gradient, are also investigated. schemes high number RANS modeling assessed against experimental data a impingement flat plate at Mach 5 unit 37 106/m. ILES has performed compression ramp case moderate numbers 38.7 103, based thickness, compared Direct Numerical Simulations (DNS).
