Hi, my problem was not with the calculation of Cp, I just didn't know is it correct to use P_out instead of p_infinity for calculation of Cp or not. because in books P_infinity is referred to...

ok thanks, another question is that when my solution reach a steady state condition, the pressure is not exactly 1 at inlet, it's for example 1.12 and also it is not 1.12 at every node on inlet...

So you mean that, in case of any differences I can add (p_out-p_in)/(rho*V^2/2) to the Cp values over the airfoil surface?

I know that this shift doesn't have any effect on lift or drag, but I am comparing my pressure coefficient results. So a shift matters here. My problem is that, because the flow is viscous and low...

calculating pressure coefficient on airfoil surface

Hi every one I am modeling an airfoil in an incompressible low Re flow! I set pressure in my outlet boundary condition as 1. I also set velocity in x and y direction at inlet. my question is when I...
