Realisable k-epsilon model in v3.22
 

I want to simulate the flow field around a rotating Savonius wind rotor. some people said they uesd Fluent and Realisable k-epsilon model getting not bad results, but in STAR-CD, there is no this model.
Can I use this model in STAR-CD v3.22? Or how can I do to make the result more similar with the experimental data. The Cp i got is about 0.16~0.27 using standard k-epsilon model.

If you upgrade to Star version 4, you will get access to the realisable k-epsilon turbulence model.
