Abstract: This paper describes numerical and experimental investigations for
the multiple shock wave/turbulent boundary layer interaction in a Mach 2
supersonic square duct. The numerical simulation is carried out with the
Harten–Yee second-order accuracy TVD scheme and the Baldwin–Lomax
turbulence model. The flow conditions are a free-stream Mach number of
M_∞ ≅ 2.0 and a Reynolds number of
Re_∞ = 2.5 × 10^7 and the flow
confinements are δ_∞/h = 0.15 (case A) and
δ_∞/h = 0.25 (case B), respectively. The
computational results for both cases show good agreement with the experimental
results. Based on these agreements, the flow quantities, which are very
difficult to obtain experimentally, are analyzed by numerical simulation.
Moreover, the effect of flow confinement on the pseudo-shock wave
characteristics is also presented.
