Step 3: Models

Models

1.   Enable the multiphase mixture model.

Models Multiphase Edit...

(a)   Select Mixture in the Model list.

  The Multiphase Model dialog box will expand.

(b)   Disable Slip Velocity in the Mixture Parameters group box.

  In this flow, the high level of turbulence does not allow large bubble growth, so gravity is not important. Therefore, there is no need to solve for the slip velocity.

(c)   Click OK to close the Multiphase Model dialog box.

2.   Enable the standard $k$- $\epsilon$ turbulence model with standard wall functions.

Models Viscous Edit...

(a)   Select k-epsilon in the Model list.

(b)   Select Realizable in the k-epsilon Model list.

(c)   Retain the default selection of Standard Wall Functions in the Near-Wall Treatment list.

(d)   Click OK to close the Viscous Model dialog box.
