Comparison of computing time between K-epsilon and RNG turbulence models
 
Dear all,

Does someone notices the difference of computing time between RNG and k-e turbulence models? In my experience, it seems the K-e model is faster than RNG model. Does someone get the same answer?

Besides, someone declares that the RNG model is more accurate, but in my simulation, there is no much difference, at least in terms of flow structure. How about your experiences?

Thanks,

Yang
