Abstract

An experimental investigation was conducted to study the transonic flow past convex corners. The mean surface pressure indicated strong inviscid-viscous interactions, and the interaction region increased with the freestream Mach number and the convex-corner angle. Unsteadiness of the interaction was characterized by an intermittent region and a local peak pressure fluctuation. The peak pressure fluctuations and the tentative boundary between the attached and separated flows could be scaled with the convex-corner angle and a second-order freestream Mach number (M_∞²η).
