personally I prefer RNG model. what about you?

Tokoda

It depends on the model, but I use V2F

RNG is a variant of k-epsilon model. So your question does not make sense.

I think you'll find that real men use cubic.

whoa so I'm a real men! Yeah...
a part this sentence...there is NOT a "best" turbulence model...the better you can choose depends on the phenomena that you must study...in presence of pressure gradients, swirl motions, curvature and similar I use k-eps CUBIC (standard)...but that's a choice...someone may prefer k-w SST if they want a "simple" model (linear) that accounts for pressure gradients...

here is for real people who're high of the gene pool and not for people who talk about a pint of Guinness in local Irish pub!
