Textbook Question
Chapter 9, Problem 18P
A laboratory wind tunnel has a test section 25 cm square and 50 cm long. With nominal air speed U1 = 25 m/s at the test section inlet, turbulent boundary layers form on the top, bottom, and side walls of the tunnel. The boundary-layer thickness is δ1 = 10 mm at the inlet and δ2 =30 mm at the outlet from the test section. The boundary-layer velocity profiles are of power-law form, with u/U = (y/δ)1/7. Evaluate the freestream velocity, U2 at the exit from the wind-tunnel test section. Determine the change in static pressure along the test section.

Air at 20°C flows at V = 80.0 m/s over a smooth flat plate of length L = 17.5 m. Plot the turbulent boundary layer profile in physical variables (u as a function of y) at x = L. Compare the profile generated by the one-seventh-power law, the log law, and Spalding’s law of the wall, assuming that the boundary layer is fully turbulent from the beginning of the plate.
Air at 20°C and 1 atm flows at 3 m/s past a sharp flat plate2 m wide and 1 m long. (a) What is the wall shear stress atthe end of the plate? (b) What is the air velocity at a point4.5 mm normal to the end of the plate? (c) What is the totalfriction drag on the plate?
We are testing a flat plate of length L = 1.125 m and width W = 0.225 m in a stream of air flowing with a velocity of 20 m/s. In test case 1, the air is flowing parallel to L and in test case 2 air is flowing parallel to W. Find:
What portion of the boundary layer flow is laminar in each case?
What is the highest laminar boundary layer thickness in each case?
Assuming the flow is entirely turbulent over the plate, calculate the drag force in both test cases
Take air density as 1.2 kg/m3 and its viscosity as μ=18×10−6μ=18×10−6 N.s/m2.

- Write down the momentum equation for two-dimensional flow along a flat plate. What are the parameters that can be calculated by solving this equation? Explain the steps used to solve this equation for both laminar and turbulent boundary layers.arrow_forwardA two-dimensional diverging duct is being designed to diffuse the high-speed air exiting a wind tunnel. The x-axis is the centerline of the duct (it is symmetric about the x-axis), and the top and bottom walls are to be curved in such a way that the axial wind speed u decreases approximately linearly from u1 = 300 m/s at section 1 to u2 = 100 m/s at section 2 . Meanwhile, the air density ? is to increase approximately linearly from ?1 = 0.85 kg/m3 at section 1 to ?2 = 1.2 kg/m3 at section 2.
