Evaluating velocity gradient in boundary layer

Please login with a confirmed email address before reporting spam

Hi all,

I would like to calculate where the condition deltaU/deltalY reaches zero thus the separation condition for a laminar-turbulent flow within a boundary layer at the wall is fullfilled.

How can I calculate the gradient along a profile and with x-axis being the position on the airfoil in x-direction and y-axis being the calculated derivate described above? So basically deriving the velocity field in normal direction with respect to the normal wall distance?

Thank you very much!
