dynamic Smagorinsky-Lilly coefficient

sla · May 29, 2009, 05:37

Hello,

I want to extract a dynamic Smagorinsky-Lilly coefficient from Fluent in order to compare the turbulent viscosity computed with the dynamic procedure with the turbulent viscosity obtained with RANS. I am solving the transport equations for my RANS model using the User Define Scalar. Is it possible to obtain the dynamic coefficient from Fluent when solving two additional transport equation?

Thank you,
Sla

Hi Sla,

Have you solved this problem? I am encountering the same thing. I will appraciate if you could share me the solution.

Best regards,
Teresa
