Abstract
Flow fields of the M2.2 jets impinging on an inclined flat plate at high plate-angles are experimentally investigated using surface pressure measurement with Pressure Sensitive Paint and Schlieren flow visualization. The present experiments show that x/Ls', (the distance from nozzle lip to the point where the jet first impinges on a plate normalized by the distance from nozzle lip to the point where jet expands the most), is still the dominant parameter defining the flow types at high plate angles between 60 and 90 degrees. The present study also shows that the flow type prediction method proposed for the plate angles between 30 and 60 degrees by Nakai et al. requires other considerations when being applied to the flows at higher plate angles. In the present experiments, a new flow type (axisymmetric jet with bubble) is also observed.
