(2) VISCOUS FLOWS AE 4120 6 c. Let now be given that the boundary layer starts at x = 0 and develops until x1 = L as a at- plate boundary layer, with ue(x) = Um (= constant). Furthermore, use for the boundary layer computations the method of Thwaites, for which a = 0.45, b = 6 and Ase], = -0.09. - Compute the boundary layer development up to x1 and determine the value 91. - Use this result to compute the required expression for ue(x) downstream of x1, such that for x > x1 the boundary layer remains on the edge of separation, A = 1391,. - In addition, determine the corresponding development of the momentum thickness. Plot the boundary layer development as function of x/L, for the interval OSx/LS4; use for this the erw VL ' N.B.: be aware that different expressions apply for x/le and for x/Lzl. dimensionless form
