How to set phase dependent turbulence models?
 
Hi, everyone,

I got information from CFX 5.5.1 manuals that I can set different turbulence model for different phases. But I find the only place I can select the turbulence model for the phases is Domain/Fluid Models form. But I can not select the turbulence model for each phase seperately. Can anyone can help me?

Following is the text from CFX Manual:

All models available for single-phase calculations are also available for multiphase calculations. It is even possible to use different models in different phases. For example, a recommended model for dilute dispersed two-phase flow uses a k-e model for the continuous phase, and an algebraic eddy viscosity model for the dispersed phase, which simply sets the dispersed phase viscosity proportional to the continuous phase eddy viscosity. </body>

Hi, when you have more than 1 domain fluid selected on the Domains form, one of the turbulence model options on the Fluid Models form will be Fluid Dependent Turbulence Model. Select this option. On the Fluid Details form you will then be able to set a different turbulence model for each phase. If you have a Dispersed Phase you should use the Dispersed Phase Zero Equation model. Hope this helps.

Thanks, Michael. Yes, it is there.
