We can model potential flow over a jellybean by using a source (Q), vortex (Γ), and sink (−Q)placed on the x axis as shown below. When combined with uniform flow (U∞), the superimposedelementary flows will model flow over a closed shape that resembles a jellybean. For the numericalparts below, use U∞ = 5m/s, Γ = 10m2/s, Q = 8m2/s, and h = 0.5m. a) Write the complex potential, F (z), for this flow, in terms of z and the given parameters (notnumerical values).b) Write the equation for the complex velocity, w(z), again in terms of the given parameters.c) Determine the location of the stagnation points in this flow, using the given numerical values.You should find three points, with two at the leading/trailing edge of the closed shape.

Consider the boundary layer over a flat plate at 45° angle as shown. The exact flow field in this configuration is described by the Falkner-Skan similarity solution with n = 1/3 (see Figure 10.8 of the textbook, the Falkner-Skan profile chart). The objective is to find the approximate solution to this problem using the Thwaites method and calculate its error. Ve 11/4 Assume that for this approximate solution the free stream velocity is U₂(x) = ax" where a is an unknown constants and n = 1/3. Use the Thwaites method to find the momentum 0/x and 8*/x displacement thicknesses as well as the friction coefficient cf = 0.5, as functions of Re₂ = Uer/v, where is the shear stress at the wall. (No need to interpolate the Thwaites method table values; you can pick the nearest numbers.) Using the Falkner-Skan profile chart approximate the friction coefficient c; (by estimating the slope of the corresponding velocity profile at the wall). How does this value compare with your prediction in part…
