OPENFOAM LES of 3D airfoil and better accuracy (6-7%error)
3 Attachment(s)
Hi,
I am running LES simulation of a 3D airfoil (runtime to date is 3 sec) my domain is attached with some results , but the default LES gave about more tham 25% (cl from exp=1.142, les=1.5)error if compared to experimental data lift and drag. ANd also the mean field (Cf) graphs are with oscillations. I was simulating at low 500,000 Re and unit freestram velocity at higher AOA to capture the laminar separation bubble.
