Rankine body (2)
(a) Plot the flow net for a Rankine body (Length = 3, Breadth = 1.35) in an uniform velocity field (horizontal direction, V = 3.5) with a source and sink of equal strength.
(b) Using 2DFlowPlus, investigate the flow pattern resulting by addition of one vortex (K = -0.1) at (X = +3.5, Y = 0) and another (K = +0.1) at (X = +4.5, Y = 0). Describe in words the physical nature of the flow.
