Note that thorough grid studies were not performed for validation cases such as this one. Some effort was made to ensure reasonable grid resolutions, but there may still be small noticeable discretization errors. Therefore, these validation results shown should be considered representative, but not "truth."

Above results are from CFL3D on the 545x385 grid. Note, however, that for these high-speed cases the computed variable $C_{\mu}^*$ is limited to 0.025 (rather than 0.0005). CFL3D used freestream turbulence intensity=0.004% (M=2) and 0.002% (M=5) and freestream turbulent viscosity (relative to laminar)=0.009 (additional details can be found in the CFL3D User's Manual, Appendix H). Please read note 5 on Notes on running CFD page. The right-hand plot is extracted from the location where Retheta=10000. Note that these are compressible code results using no compressibility corrections. Furthermore, as for other two-equation model cases posted on the TMR website, the $- (2/3) \rho k \delta_{ij} \partial u_i / \partial x_j$ term in the production was ignored (often the default for codes whose predominant applications are low-speed or transonic cases). Generally speaking, for high-speed cases, this term could be significant. However, testing for the 2DZPH case with the SST-Vm model has shown that including or ignoring this term only makes relatively minor differences (on the order of the differences seen between the codes).

Note that this model is currently assigned MRR Level 1 for the purposes of this website. This is because at this time the TMBWG has results for this model from only one code. The results on this page are therefore not necessarily reliable until additional independent code(s) can be used to verify the model implementation.
