WebI am doing a research on a NACA 0012 airfoil. All simulations are done in OpenFOAM with a moving mesh (dynamic mesh), I use the pimpleDyMFoam solver. My problem is, the lift is around 2.7 to 3. I suspect that is to high, I expect it to be around 2. The vorticity is in good accordance with the experimental results.

WebIf a is chosen such that C L = 0, C MAC = C Ma and hence pitching moment coefficient about an axis at ZERO LIFT equals the pitching moment coefficient about Aerodynamic Centre. Thus, C MAC is also designated as C M0, the moment coefficient at ZERO LIFT. Centre of Pressure: From equation [II], M LE = M AC - [L · cos (α) - D · sin (α)] · x AC.
