Turbulence Model
hi, every1 i am using star-design to do my final year project ,i was ask to very the turbulence model which are ke model and constant viscosity model. however in the option i can only find ke model on/off, how do i use constant effective viscosity model then ? ( is it just turn the ke off and density to constant >? )

Re: Turbulence Model
Hi,
what do you mean for costant viscosity models? I don't understand...you're speaking about turbulence model but you want a model where you consider a costant viscosity for your liquid? If I'm not wrong every turbulence model consider a variable viscosity in the liquid...it's implicit in the turbulence phenomena...then you can choose to use a scala relationship between viscosity and shear stress or not...but that's another question... Plase be more specific Regards |
Re: Turbulence Model
Star Design is a very pared down CFD program. You can chose either k-epsilon turbulence model or laminar flow. Star-CD offers a much wider range of tubulence models. Constant viscosity is the most simple one. So if you are to compare those two models you should use Star-CD.

Sorry for my previous message, now I understand...
