Abstract

The laminar-turbulent transition process has been documented in a concave-wall boundary layer subject to low (0.6%) free-stream turbulence intensity. Transition began at a Reynolds number, Re_x (based on distance from the leading edge of the test wall), of 3.5 × 10⁵ and was completed by 4.7×10⁵. The transition was strongly influenced by the presence of stationary, streamwise, Gortler vortices. Transition under similar conditions has been documented in previous studies, but because concave-wall transition tends to be rapid, measurements within the transition zone were sparse. In this study, emphasis is on measurements within the zone of intermittent flow.
