This paper describes an investigation by numerical simulation and experiment on the structure and characteristics of the multiple shock waves and turbulent boundary layer interaction, that is, pseudo-shock wave in a Mach 2 two-dimensional channel. The numerical simulation was carried out with Harten-Yee's second-order accuracy TVD scheme and Baldwin-Lomax's algebraic compressible model for turbulent flows. Comparison between the numerical simulation and experimental ones were well consist with each other. Base on this consistency, the flow quantities, which are very difficult to obtained by experiment, were analyzed by numerical simulation. These analyses are very valuable to understand the detailed structure and characteristics of the pseudo-shock wave.
