Question

25 Air at 25Â°C flows over a flat plate with a velocity of 2 m/s. Using Blasius' exact solution, find: a) The Reynolds number and boundary layer thickness at 20 mm from the leading edge and also at the end of the laminar boundary layer. b) The rate of growth of the boundary layer at the two points in (a) above. The thickness Î´/x = 5.48/âˆš(VRe_x), the displacement thickness Î´/x = 1.828/âˆš(VRe_x), and the B.L momentum thickness Î¸/x = 0.731/âˆš(VRe_x), and the skin friction coefficient cf/x = 0.731/âˆš(VRe_x). Repeat the same calculations using a 3rd order velocity profile. Compare the results with those obtained using Blasius' exact solution. Comment on the accuracy of the results in all three solutions.
