post processing of k-epsilon, u', v', w'

April 15, 2006, 01:12

Hello.

Thanks for your interest in reading my question.

Do you know why in k-epsilon model we cannot get u', v', w'? Is there any way that we can extract them?

Thanks, Mazyar

Hi,

The k-e class of models are based on iso-tropic turbulence. That means u'~v'~w'.

And there is no need to calculate these quantities for solving the k-e equation, so you will not able to see them in Fluent.

Since u'~v'~w'~ pow(k,1/2), we can get a feel of this quantities by ploting k.
