Abstract
Flow fields of the supersonic jet impinging on a 45-degrees inclined flat plate are experimentally investigated using the Pressure Sensitive Paints [PSP] and Schlieren image visualization techniques. Temperature Sensitive Paints [TSP] are used to remove the effect of the temperature variation on the flat plate. The PSP and Schlieren result shows that the variation of the Nozzle-Plate Distance changes the shock wave configurations in the flow fields. Additional visualization using oilflow technique reveals that the stagnation bubbles generate two pressure peaks around the stagnation area on the flat plate at certain nozzle-plate distance.
