Separation and Flow Unsteadiness Control in a Compression Corner Induced Interaction Using Mechanical Vortex Generators; Effects of Vane Size and Inter-Device Spacing
2022
Physics of Fluids
An experimental investigation was conducted to control separation characteristics of a 24o compression corner induced interaction in a Mach 2.0 flow using an array of mechanical vortex generators (VG) with rectangular vanes (RRV) placed 6.8 δ upstream of the interaction. The objective was to study the effect of (i) inter-VG spacing ( s/h=12, 9.5, 8.0, 6.1, 5.7, 5.5, 4.9, 4.7) (ii) vane chord length ( c/h=7.2, 4.2, 3.0) and vane angle ( α=24o, 20o, 18o, 16o) in controlling the interaction and on
