Abstract:

Experimental observations of transition from laminar to turbulent boundary layers in shock tubes is reviewed. The seemingly contradictory behavior is viewed in the light of transition behavior in other ground facilities. Comparison with linearized stability theory of Ostrach and Thornton indicates that transition takes place precritically, presumably due to finite disturbances. This fact could make shock tubes a convenient milieu for studying the elusive regime where high cooling is matched with high unit Reynolds number and controllable roughness. The paper was part of the background material for the Workshop of Specialists in Boundary-Layer Transition, held in November 1971 at the Aerospace Corporation, San Bernardino, California.
