Set Up Disperse Multiphase Modeling

Disperse multiphase modeling gives you the capability to simulate the momentum exchange between a carrier field and a dispersed field. When simulating multiphase flows using the disperse multiphase model, the carrier field has to be a fluid and the dispersed field can be of any medium.

From the Flow ribbon, click the Physics tool.

Figure 1.
Under the Physics models settings, change the flow radio button to Multiphase.
Change the Multifluid type to Disperse.
Select a disperse material model from the drop-down menu or click Material Library to create, edit, and manage custom material models.

After setting up the disperse multiphase physics, you have the option to set the carrier fluid volume fraction in all inlet and outlet (backflow condition) boundaries.

In addition, you can select the carrier volume fraction as a variable when defining initial conditions in the Solution ribbon.
