Hey all,
After researching for some days, I haven't been able to answer if the Wilcox k-ω turbulence model uses Enhanced Wall Treatment (EWT) in CFX as it does so in Fluent. I know its advantages over the k-ε model but I don't know whether it uses this EWT in CFX also. I hope someone could help me out in this. Thank you in advance for any answer. |

I had already read that page but it really doesn't tell you if EWT that is used in Fluent is also used in CFX... Or maybe it has a different name in CFX? |

What I want to know is if this "automatic wall treatment" in CFX does the exact same thing in CFX as the EWT does in Fluent: does the same changes from log-law wall treatment to Low-Reynolds number implementation the same way that FLuent does with its "EWT"? I just want to know if this "Automatic wall treatment" in CFX is just the way CFX named the procedure that Fluent named "EWT"... I want to know if they're equivalents, so to speak. |
