Abstract
The turbulence phenomena in multiple shock wave/turbulent boundary layer interactions in a square duct have been investigated using a two-component laser Doppler velocimeter (LDV). The free stream Mach number M ∞, flow confinement δ ∞/h and unit Reynolds number Re just upstream of the interaction were of 1.78, 0.3 and 13×106 m−1, respectively. First, the interaction flow fields were visualized by using schlieren photographs and laser holographic interferograms. Second, the time-mean and fluctuating velocity fields were explored in detail using the LDV. Spatial distributions of turbulence intensity, Reynolds shear stress, turbulence kinetic energy and turbulence production are presented.
