Hi, Foamers,

I am trying to do hurricane boundary layer CFD simulation using OpenFoam, one of the problems is setting bottom boundary condition.

I am trying to set up a "partial-slip" wall boundary condition for the simulation. according to the empirical relationship, the surface stress is calculated based on near-surface velocity. this makes wall boundary condition in OpenFoam is invalid here.

I notes that there is a partial slip boundary condition in OpenFoam, but I can not fig out how this is implemented since the description for this boundary condition in User's guide is vague.

any suggestion?

thanks a lot

Hi,

I am in Tongji University, and I may help you for this partial slip boundary condition.

I use msn: zhoubinwx@hotmail.com
