Boundary-layer separation occurs when the shear stress

at the surface becomes zero. Assume a polynomial representation for the laminar boundary layer of the form, u/U 5 a

1 bλ 1 cλ2 1 dλ3

, where λ 5 y/δ. Specify boundary conditions on the velocity profile at separation. Find appropriate

constants, a, b, c, and d, for the separation profile. Calculate

the shape factor H at separation. Plot the profile and compare

with the parabolic approximate profile.
