How can I find eddy size distribution in ANSYS Fluent?

02 February 2021 1 937 Report

Hi everyone,

I'm simulating a 3D turbulent pipe flow using the SST K-W turbulence model in ANSYS Fluent. Is there any quantity among the postprocessing quantities that represent "eddy size" or "eddy length scale"? If there is not such a quantity, How can I define it in Fluent?

Thank you.

Dear Hossein Rabieh

You have to define for example your desired Kolmogorov scale through UDF.

Cheers,
