When a wall has some motion normal to the wall then streamlines can hit the wall. Just have a play with it and you will see. I do not feel like writing a mathematical proof of it as it is obvious...

If you don't want lines through walls you should look at each section in its own frame of reference. Look at the stationary sections with velocities in the stationary frame of reference, look at the...
