Unateady flow over airfoilHi every one
I am simulating an airfoil with plunge oscillation and the airfoil, when it has natural shedding in an incompressible low Re flow. The flow is unsteady and I wanna calculate Cp at different times(some selected time steps). Now I have some questions: 1) when I want to calculate cp in a special time for airfoil with natural shedding, can I use the simple formula for calculating Cp? I mean Cp=(p-p_inf)/q which P_inf is the pressure in the far field boundary! 2) when I am applying force oscillation, for example plunge oscillation, how can I calculate Cp again? does anyone know how to calculate Cp in this case? Thanks for any words! |
