29.6. Coupling of Eulerian Wall Film with the VOF Multiphase Model

To couple the Eulerian Wall Film and the VOF multiphase models, follow these steps:

  1. Enable and set up the Eulerian wall film model and the VOF multiphase model as appropriate for your case.

  2. In the Eulerian Wall Film dialog box, enable Phase Coupling (Solution Options group box) as shown in Figure 29.2: The Eulerian Wall Film Dialog Box - Model Options and Setup tab (with Phase Interaction).

  3. In the Phase Interaction tab, enable VOF Coupling.

  4. In the Transition Base group box, select either Volume Fraction or Height Fraction transition criteria type. See Setting Eulerian Wall Film Model Options for more information about these options.

  5. In the Wall dialog box, go to the Wall Film tab.

  6. In the VOF Interaction tab that becomes available after VOF Coupling is enabled, enable Film VOF Coupling and set parameters for the EWF and VOF model coupling as described in Setting Eulerian Wall Film Boundary, Initial, and Source Term Conditions.

For theoretical information about the EWF/VOF coupling, see Coupling of Eulerian Wall Film with the VOF Multiphase Model in the Fluent Theory Guide.
