In this paper, first, the formation process of pseudo-shock wave in a straight square duct is shown using high speed schlieren films. Second, the relation between the locations and structures of pseudo-shuck waves is discussed using wall pressure distribution measurements and schlieren pictures. Third, the internal structure of ă-type pseudo-shock wave is investigated in detail by total pressure profile measurements.
