Which turbulence model wor a mult-element wing?

Zweeper · February 20, 2010, 10:20

Hello everybody!

I will simulate the flow about a multi element wing (in 2d as well as in 3d) and i ask myself which turbulence model the most suitable is for this case.

my teacher told me the k-epsilon is a good one because it is of course very fast and commonly used. but i THINK (when i consider the infos in the fluent documentation etc) that the k-omega sst with transitional flow is better for the flow about a multi element wing.

Maybe someone can confirm this or give me some reasons why the k-omega is not so good for this case (and maybe also which model i should consider instead)?

already big thanks and regards!
