simulating wing stall,what kind of turbulence model is recommended
hi,i am donging a 3d wing(airfoil is e197,Re=203771).what kind of turbulence model is recommended or just using the none(laminar)。simulation type should be steady or transient
|
If you are donging a fairly typical airfoil at Re=2e5 then it is likely that turbulence transition effects are going to be significant. As a first go try SST, but you will probably need to activate the turbulence transition model.
|
thank you very much
|
so what about Gamma model and Gamma Theta model
|
What about them?
|
Sorry,I mean how to choose the transitional turbulence, when I use the sst model to simulate my job I had mentioned above.
there are four choice: fully turbulent specified intermittency gamma model gamma theta model And for Gamma model how much should the Transition Onset Reynolds Number be?What about 50000 for Eppler 197? Thanks |
The default gamma theta model is generally the one to go for. Unless you know what you are doing here leave all the settings at default values.
