Stokes Law

  1. Dec 11, 2007 #1
    Hi -
    Is it possible to derive Stokes law or is it an emprirical law.?
    http://en.wikipedia.org/wiki/Stokes'_law
    I was thinking of using the Navier-Stokes equations but i dont want to start out
    if it impossible..
    Thx.

    So can I derive it analytical or do I have to use numeric methods alias finite element..?
    Well I will try to do some calc tomorrow.. shouldnt be that hard.. thx

    Yes it is possible to derive Stokes law analytically but you have to work a bit intuitively to get the the appropriate velocity profile equations. This seems to include invoking Occam's razor to justify applying a zero valued coefficient to the squared terms in the V.P. equations.
    Cheers,
    T.S.
