Hi everyone.
I'm making 2D cfd analysis of a paraglider.
I tried lots of solution methods but interestingly my Pressure Coefficient distribution and my static pressure distribution are %99 same. Is there anyone who has any idea about this?
Thank you for your answers.

Hi,

With the pressure coefficient defined as C_p  = \frac{p- p_\infty}{\frac{1}{2} \rho_\infty V_\infty ^2 }, wouldn't you expect to find that this follows the same development along the airfoil as the static pressure (p) does? (As far as I can see, all the other variables are constants for a given flow.)
