Unformatted text preview: ii. Is there a velocity potential describing this flow? 5) The velocity potential φ = x + 0.1 ln(r) , where r = sqrt(x^2+y^2), corresponds to a uniform free stream flow over a point source (in 2D). i. Find the x,y velocity components (u,v) ii. Find the point where u=v=0 (i.e. the stagnation point). iii. Plot the velocity vectors over a domain from x=-0.2 to x=+0.3 and y=-.3 to +.3. iv. Try to draw a line separating fluid coming from upstream from that coming out of the source at x=y=0...
