KR371: How can I adjust the turbulent Schmidt and Prandtl number for species in CFX ?
|
In order to allow for independent turbulent Prandtl and component turbulent Schmidt numbers, the following needs to be added at the top of the CCL: RULES: OBJECT: COMPONENT CONTEXT: Transport Equation Optional Child List = TURBULENT FLUX CLOSURE END END END Then, turbulent Schmidt numbers may be defined individually for components as follows: FLOW: DOMAIN: FLUID MODELS: COMPONENT: <component name> Option = Transport Equation TURBULENT FLUX CLOSURE: Option = Eddy Diffusivity Turbulent Schmidt Number = <real> END END END END END If the TURBULENT FLUX CLOSURE singleton is missing for some of the components, these default to enthalpy turbulent Prandtl number as before. |
