Forces on spherical body
 

Hi, friends:

I'm looking for research on forces on spherical body subject to non-uniform, unsteady viscous flow.

Actually I'm trying to find the instantaneous force on an individual partical in the wave boundary layer on seabed, so that I can get some insight on the instantaneous entrainment of sediment particals.

Theoretical, experimental, numerical even empirical approaches are all welcome. Lamilar and turbelent flow, with and without separation on the lee side.

All comments are appreciated,

Thank you very much,

Wen Long
