RNG-k-epsilon with realisable contraint
 

Hello Everybody,

does anybody know if the RNG-k-e model has a realizable constraint? If not, then I am wondering if it even need one, i.e. are there a other properties which makes the need for readability redundant?

Cheers in advance

Realizability constraint is a constraint on the normal Reynolds stresses that the model must satisfy for it to be realizable. See here http://www.cfd-online.com/Wiki/Realisability_and_Schwarz%27_inequality

Check the Reynolds normal stresses from RNG k-e simulation to check if the model is realizable.
