The run script Allrun.sh settings is following:
turbulence=RANS solver=simpleFoam mode=incompressible wall=lowRe endTime=0.05 deltaT=0.00001 NProc=6 mesh=229k turbulenceModel=v2f
Figure: NACA4412: Turbulence model . Mesh 229k cells. Pressure coefficient versus dimensionless x-axis. The x-axis was divided by the length of the chord of the NACA4412 profile. Dataset NASA exp is the experimental data. Dataset NASA SA is the NASA RANS simulation results with Spalart Allmaras turbulence model.
