jos.lc123 is on a distinguished road
How does a curvature induces variation in pressure gradient in streamwise direction? I'm trying to deduce by math/intuition but I couldnt get it.

Start from a simple case, inviscid steady flow.
Then consider the velocity along the curvature of an airfoil and apply Bernoulli to deduce the pressure.
When you go to consider the BL, remember that the pressure in normal direction is almost constant (Depending on the viscosity value).
