flow velocity

I am trying to obtain the flow velocity in two dimensions $\displaystyle u(x,y) $ for the case of a incompressible viscous flow around a circle inside a two dimensional channel. The equations to solve are:

$\displaystyle \mathbf{\nabla} p = \mu \mathbf {\nabla}^2 u $

$\displaystyle \mathbf{\nabla} \cdot \mathbf{u} = 0 $

The idea is to calculate first the green function in two dimensions. How can I calculate this green function?
Which will be the boundaries condition far from the circle?

Why dont you post this in the math help forum? You are sure to get better guidance there. Believe me there are geniuses on the prowl there looking for such stuff!
And could the question be a little clearer with respect to the position of the circle in the channel?
