The test section of a low speed wind tunnel is a square duct with cross section of 7 cm × 7 cm. The wind tunnel has a uniform velocity of U = 30 m/s at the test section inlet (location 1). Due to the development of boundary layers on the sides of the wind tunnel, the flow accelerates in the inviscid core. If the displacement thickness at a distance 30 cm downstream of the inlet (location 2) is 1 mm, determine the change in static pressure in the test section, p2 – p1 [Pa].

A 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. The diverging duct is 2.0 m long and is 1.60 m high at section 1 (only the upper half is sketched in Fig. P9–36; the halfheight at section 1 is 0.80 m). (a) Predict the y-component of velocity, ?(x, y), in the duct. (b) Plot the approximate shape of the duct, ignoring friction on the walls. (c) What should be the half-height of the duct at section 2?

Fluid Mechanics Problem The clamping forces on a horizontal pipe-bend are measured to be 1050 N in positive x-direction and 850 N in positive y-direction. Calculate the "one time lossfactor K" for the pipe-bend based on the velocity in the narrow part of the pipe-bends beginning which is 2 m/s. The pipe diameter at the beginning of the bend is 15 cm and 25 cm at the end of the bend. There is water that flows through the pipe-bend with temperature 20 degrees Celcius.

A group of students is designing a small, round (axisymmetric), low-speed wind tunnel for their senior design project. Their design calls for the axial component of velocity to increase linearly in the contraction section from uz, 0 to uz, L. The air speed through the test section is to be uz, L = 120 ft/s. The length of the contraction is L = 3.0 ft, and the entrance and exit diameters of the contraction are D0 = 5.0 ft and DL = 1.5 ft, respectively. The air is at standard temperature and pressure. (a) Verify that the flow can be approximated as incompressible. (b) Generate an expression for the radial velocity component ur between z = 0 and z = L, staying in variable form. You may ignore frictional effects (boundary layers) on the walls. (c) Generate an expression for the stream function ? as a function of r and z. (d) Plot some streamlines and design the shape of the contraction, assuming that frictional effects along the walls of the wind tunnel contraction are negligible.
