Stream function from potential ..
Posted:

All,
I have a velocity potential (the gradient of this function is the velocity field) given by :
phi(x,y) = 1/sqrt((y1)^2 + x^2) + 1/sqrt((y+1)^2 + x^2) + k x
where k = constant. I am interested in finding the orthogonal function psi(x,y) so that psi(x,y) = constant on a stream line. Another way to state this is to say : find a function psi(x,y) such that
psi_x = phi_y and psi_y = phi_x
where the subscripts stand for partial derivatives.
Thanks for your help.
S.
