turbulence viscosity

November 10, 2006, 20:57

HI, Can anyone tell me how do I find turbulence viscosity ratio in fluent, for my problem. I am using the SA model. All I need to specify in SA model is the turbulence viscosity right?

Thanks!

Dear Rekha,

turbulent vicosty ratio is difined as ratio of turbulent viscosity to laminar viscosity. thus you can give the value in between 1 - 10.

otherwise select intensiy and hydraulic diameter, give intensity in between 1-10%,

i hope this help you..
