2D NACA 0012 Airfoil Validation Case
K-e-Rt Model Results
Link to k-e-Rt equations
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."
(See the NACA 0012 Numerical Analysis Case for a
representative verification exercise of this airfoil case.)
Above k-e-Rt results are from CFD++
on the 897x257 grid.
CFD++ used freestream turbulence intensity=0.5% and freestream turbulent viscosity (relative to laminar)=10.
Please read note 5 on Notes on running CFD page.
Note that these are compressible code results
at "essentially incompressible" conditions of M=0.15.
There may be a very small influence of compressibility.
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.
