Setting Up the Phase Interaction

Using the Multiphase Interaction model, you can define the interaction between the oil phase and the particle phase.

When you create a phase interaction, you select the continuous phase first, and then the dispersed phase. When you select the dispersed phase, you also choose the phase interaction type. In this simulation, the continuous phase is Oil, the dispersed phase is Particles, and the phase interaction type is Continuous-Dispersed Topology.

To define the phase interaction:

  1. In the Suspension continuum, right-click the Models > Multiphase Interaction > Phase Interactions node and select New > Oil > Particles (Continuous-Dispersed).
The initial volume fractions are 0.45 for the oil phase and 0.55 for the particle phase. The mixture is initially at rest.
  1. Select the Suspension > Models > Multiphase > Phases node and set the following properties:
    Node Property Setting
    Oil > Initial Conditions > Volume Fraction > Constant Value 0.45
    Particles > Initial Conditions > Volume Fraction > Constant Value 0.55
  2. Save the simulation.
