Velocity distribution

  1. Mar 1, 2005 #1
    The water in a river is flowing at constant velocity. Beneath the surface and lying across the river there is a cylindrical wood. If you can assume that the wood is infinitely long how do you determine the velocity distribution of the water around the wood?

    any ideas?

    2-D potential flow about the circular cross-section should do it.

    If you are assuming non-zero viscosity then that is a very difficult problem.
