Using MATLAB ,To study the flow around a Rankine oval, a source and a sink of equal strength can be combined with a uniform flow. The streamfunction and potential is given by = U y Q 2 tan1 ( 2ay x2 + y2 a2 ) = U x + Q 4 ln [ (x + a)2 + y2 (x a)2 + y2 ] where (a, 0) and (a, 0) are the location of the source and sink respectively. (a) Plot the flow net of the Rankine oval. (b) Indicate the stagnation points on the flow net clearly. (c) On the same figure also plot the streamlines which indicate the surface of the Rankine oval show the answer in matlab
