Abstract

The laminar-turbulent transition due to the interaction of an upstream aerofoil wake on a downstream flat plate boundary layer is studied experimentally. Measurements conducted on the flat plate boundary layer for four different aerofoil heights (hw ) above the flat plate demonstrate the evolution of both a non-modal disturbance profile and a longitudinal streaky structure in the pre-transition region. Sensitivity to aerofoil height suggests that this experimental arrangement would enable more systematic investigations of the receptivity mechanisms in multi-element configurations than possible using grid turbulence-induced transition.
