Doublet Flow Calculations

06/22/2009 11:25 AM

The stream function for a plane potential incompressible doublet flow is supposed to be

psi = -(Q/2pi)*arctan((2arsin(theta)/(r^2-a^2))

Why?

Q = superficial flow rate (volume flow rate/unit length)

r, theta = polar coords

2a = length of the doublet.

Thanks, people.
