Stallion 3D - Transonic Flow Results
The following computations were performed using
Stallion
3D, the new fully integrated three-dimensional compressible
flow analysis tool. The software features an automatic cartesian
grid scheme for immersed boundaries coupled with an accurate compressible
flow solver based on the Euler equations.
The present results are for a moderate sized grid of
200,000 cells with about 20,000 boundary cells. The grid was
generated for the full wing.
The experimental results are from Schmitt and Charpin's Argard Report,
"Pressure Distributions on the ONERA-M6-Wing at Transonic Mach
Numbers," experimental Data Base for Computer Program Assessment. Report
of the Fluid Dynamics Panel Working Group 04, AR-138, May 1979
Computational results were further compared to the pertinent
test case of the
NPARC
Alliance Validation Archive. After 2,200 interations, Stallion 3D produced
a Cl of 0.274 and pressure Cd of 0.0189 (based on planform area). The WIND
code results in a Cl of 0.2657 and pressure Cd of 0.0112.
CFL3D reports a Cl of 0.2657
and Cd of 0.01724 (total).
