1 35 * An Experimental Study on the Characteristic of ean Flow in Supersonic Boundary Layer Transition Shoji SAKAUE, Department of Aerospace Engineering, Osaka Prefecture University ichio NISHIOKA, Department of Aerospace Engineering, Osaka Prefecture University (Received 3 September, 8; in revised form 9 arch, 9 To obtain a better understanding of the mechanism for supersonic boundary layer transition, we examine a ach.86 supersonic boundary layer along a small tunnel nozzle wall with rectangular cross section using Pitot-tube and quantitative schlieren optical system calibrated by wedge prism method. ean flow profiles in transition process are obtained by measuring distributions of density gradients. The results clearly show that near-wall density gradients start to increase at the beginning of transition, suggesting the occurrence and growth of disturbances which carry the mainstream fluid to the wall neighborhood and the near-wall fluid to the outer edge. It is also shown that inclined vortical structures our schlieren system visualizes are similar to the structures observed in supersonic turbulent boundary layers. Furthermore, the result obtained by the quantitative schlieren method indicates the transition to occur earlier compared with the corresponding obtained at the span center of the tunnel. It is suggested that the transition occurs near the nozzle corner region first and the turbulence is spread by a process of transverse contamination.
