AbstractIn order to predict the flowfield of three-dimensional wall jets, an extended non-linear constitutive relation of the Reynolds stress is incorporated into the Shear Stress Transport turbulence model. The JAXA-developed FaST Aerodynamic Routines (FaSTAR) is used as a compressible-flow solver. In this study, computations of three-dimensional wall jets are performed by the proposed turbulence model and its quantitative success is shown. Then, we examine the sensitivities of maximum velocity and velocity half-widths to the Reynolds number and Mach number, respectively.
