Are there any advantages to the k-epsilon model? This models seems to still be a widely used model despite its disadvantages. In my (limited) experience, its validity only for fully turbulent flows and non-separated flows seems to narrow its applicability quite a bit.

Based on the advantages of sst and my experience, there does not appear to ever be any reason to choose k-epsilon over sst. Is this correct? What are the disadvantages of using sst?

Thanks in advance for any information. I would really like to determine the answer to these questions so i would be very grateful for any responses.
