Axisymmetric Separated Boundary Layer 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.
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."
The plots compare the SSTm results from
three different independent CFD codes - CFL3D, FUN3D, and TURCOM - to experimental data.
CFL3D and FUN3D used freestream turbulence intensity=0.088% 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.
These results are from the second-finest grid (713x193).
All three codes yield nearly identical results.
Note that these are compressible code results at "essentially incompressible" conditions of M=0.08812.
There may be a very small influence of compressibility.
The data files from CFL3D are given here:
driver_cfl3d_cp_sst.dat,
driver_cfl3d_cf_sst.dat,
driver_cfl3d_vel_sst.dat,
driver_cfl3d_uv_sst.dat.
(Note: the profiles have been interpolated using Tecplot software onto pre-set points, that may or may
not correspond to the actual grid points or grid cells used in the computation.)
A typical CFL3D input file is:
driver_cfl3d_typical_sst.inp.
A typical FUN3D input file is:
fun3d.nml_typical_sst_2.
