I am working on the following problem:  very low reynold's number flow
through an axisymmetric pore with a sinusoidally varying radius.  Inertial
terms can
be  neglected.  I am familiar with some numerical solutions.  The problem
is somewhat analogous to the classic problem of flow around a sphere for
which
Stokes derived a solution.  It would thus seem that an analytical solution 
would be tractable.  I would like to know if anyone is familiar with
analytical solutions or other work on this problem.  Any other comments
would also be welcome.  For now I plan to use the FIDAP Navier-Stokes
solution package to solve the problem numerically, but a closed form
analyitical solution would be wonderful. 
I've posted this request only to sci.geo.fluids.  Are there any other
appropriate groups I'm not familiar with? 

Thanks,
