(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A wind flows along the horizontal ground with strength U and over a long semi cylinder. The flow can be described using two dimensional potential theory

Find the velocity potential

2. Relevant equations

3. The attempt at a solution

I'm not sure what to do.

The equations for velocity potential are

v_{r}= [tex]\frac{d\phi}{dr}[/tex] and v_{[tex]\theta[/tex]}= [tex]\frac{d \phi}{rd \theta}[/tex]

Can I say that there is no wind flowing trough the walls so v_{r}= 0

and that v_{[tex]\theta[/tex]}= U because air is incompressible?

I'm not sure at all.
