k-epsilon help
 

Hello,

I am kind of new to OF. I've been able to build a case for my purposes (flow around an object), but i want to explore more on the matter and need some help

I am building my case using the Simple solver (im modeling for incompressible flow). i used one of the tutorial cases as my base, but i was wondering if anyone can point out to any resources that explain how to choose/compute the initial boundary conditions and values for the turbulence parameters ie epsilon, K, nut, nuTilda etc. How can i determine which bc to use and/or what value to assign. Any help is much appreciated.

Thanks,

Ricardo
