For Shear Stress Transport (SST) turbulence model, an anisotropic algebraic constitutive relations for the Reynolds stress tensor are integrated in CFD solver developed in JAXA called FaST Aerodynamic Routines (FaSTAR) that is three-dimensional compressible Reynolds averaged Navier-Stokes code. Using these relations, we calculate computations of three-dimensional wall-jet. As compared with experimental data, it is found that a wide spreading in spanwise direction in cross section of jet axis can be predicted and the obtained ratio of velocity half-width is improved by taking into account the anisotropy. The obtained results of SST turbulence model with algebraic constitutive relations agree quite well with those obtained in experiment.
