3D Supersonic Square Duct Validation Case
GLVY-RSM-2012 Model Results
Link to GLVY-RSM-2012 equations
Note that thorough
grid studies were not performed for validation cases such as this one.
Especially for 3-D cases, there may still be
significant discretization errors. Therefore, these validation results shown should be considered
representative, but not "truth."
The above GLVY-RSM-2012 results are
from the code aerodynamics.1.0.3 on the 481x81x81 grid.
The inflow is uniform (except for the no-slip boundary-condition at the walls; no inflow boundary-layers), with a turbulence intensity = 1% and a
freestream lengthscale = 0.05 m = 50 mm, which is roughly the duct's height
(see Note 4 on
GLVY model description page).
As can be seen from the last figure, this Reynolds stress model exhibits secondary circulation near the corners.
(In the figures, uCL
is the u-velocity at the center point 2y/D=2z/D=1 in whatever x-plane you are plotting.)
Some of the data files from A3D are given here for reference:
A3D_result40_GLVY.dat,
A3D_result50_GLVY.dat,
A3D_cf50_GLVY.dat.
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.
