PSP Analysis of Circular Jets Impinging on an Oblique plate

This study was conducted for an aerospike nozzle and to analyze the phenomena of the jet impingement, which was spout out from a circular nozzle with four or eight holes to a flat plate. The impingment was undertaken to be perpendicular and oblique to the plate. If the distance between the flat plate and the nozzle becomes close, an usual PSP analysis is difficult because the source of light, a camera and the nozzle can not be set up for the PSP measurements. Therefore, the pressure on the plate was observed from the back side of the a flat plate. Furthermore, the visualization of the impingement jet flow was studied by the oil film method.
