Consider a uniform flow with velocity U in the positive x direction combined with two free vortices of equal strength located along the y-axis. Let one vortex located at y a be a clockwise vortex and the other at y a be a counterclockwise vortex, where K is a positive constant. It can be shown by plotting streamlines that for Ua/K 2 the streamline forms a closed contour, as shown in Fig. P6.70. Thus, this combination c can be used to represent flow around a family of bodies (calledKelvin ovals). Show, with the aid of a graph, how the dimensionlessheight, H/a, varies with the parameter Ua/K in the range 0.3Ua/K 1.75.
