Wall jet similarity of impinging planar underexpanded jets [PDF]
International Journal of Heat and Fluid Flow, 2020 Velocity profiles and wall shear stress values in the wall jet region of planar underexpanded impinging jets are parameterized based on nozzle parameters (stand-off height, jet hydraulic diameter, and nozzle pressure ratio). Computational fluid dynamics is used to calculate the velocity fields of impinging jets with height-to-diameter ratios in the ...
