The internal structure of a pseudo-shock wave in a straight square duct was visualized using color shlieren pictures and laser holographic interferograms, and the density distributions in the pseudo-shock wave were clarified. Next, the velocity distributions in the pseudo-shock wave were measured using 2-dimensional LDV, and the effect of wall boundary layers on the structure of pseudo-shock wave was clarified.
