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? Last edited by laephy; Aug 26th 2009 at 06:16 AM.

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?
