2D Zero Pressure Gradient Flat Plate Validation Case
SSTm Model Results
Link to SSTm equations
Previously on this page the results were reported as SST solutions, but more properly they should be referred
to as SSTm. Essentially no difference is expected.
Above SSTm results are from CFL3D on the 545x385 grid;
FUN3D results on same grid are almost identical.
Both CFL3D and FUN3D used freestream turbulence intensity=0.039% 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.

Flat Plate Verification case.
The right-hand plot is extracted from the location where Retheta=10000.
Note that these are compressible code results
at "essentially incompressible" conditions of M=0.2.
There may be a very small influence of compressibility.
Note that use of SST, SSTm, SST-V, or SST-Vm
yield nearly identical results for this case.
The CFD postprocessed data files are given here for reference:
sst-cf_cfl3d.dat and
sst-upyp_cfl3d.dat.
A typical CFL3D input file is:
cfl3d_typical_sst.inp.
A typical FUN3D input file is:
fun3d.nml_typical_sst_2.
