Problem 4 Consider an oval located in x-axis and subjected to a uniform flow moving in positive x-direction. Determine: a. Velocity components. b. The locations of the stagnation points c. Draw the stream and potential stream functions if U=1,a=0.1, and q=1. Uniform flow A source or sink Doublets (z)=Uz =Ux =Uy (z)=2qln(z) =2qln(r) =2q (z)=z =x2+y2y =x2+y2x Problem 4 Consider an oval located in x-axis and subjected to a uniform flow moving in positive x-direction.
