Abstract

The physical relation between the geometry and the flow topology of the wake of a micro ramp is investigated by means of a parametric study. Various micro ramp geometries are placed in a supersonic turbulent boundary layer at a free-stream Mach number of 2. The flow field is measured with schlieren and Particle Image Velocimetry (PIV). The effect of geometry on different aspects of the flow field is studied and from this a physical model of the flow phenomena is formulated. This model includes the concept of captured momentum, a simplified expression which allows relating the geometrical features to vortex circulation and from this a new scaling factor is proposed. The physical model is validated with the experimental data.
