How Fluent simulate lake flow under wind drag？

billowboy · June 2, 2009, 04:46

hello,everyone:

I want to add the wind effect to a lake surface. It seems that moving wall boundary condition can not solve this. how can i do it？thank you!

If I need to use UDF? the surface shear stress can be expressed as: Stress = F*abs(Vwind-Vwater)*(Vwind-Vwater), where F is the friction coefficent.

no one knows? i really want to figure it out

maybe you could read some papers in Journal of Fluid Mechanics about your topic
