Creating Phases and Selecting Phase Models

Create two new phases, specify them as air and particle, and set the appropriate material properties for each phase.

To create the phases and select the phase models:

Create the gas phase.
  1. In the Physics 1 continuum, right-click the Models > Multiphase > Phases node and create a new phase.
  2. Rename the Phase 1 node to Air.
  3. For the Air phase, select the following models:

    Group Box

    Model

    Enabled Models

    Laminar (Selected automatically)

    Flow (Selected automatically)

    Material

    Gas

    Equation of State

    Constant Density

  4. Click Close.

Create the particle phase.

  1. Create a second phase and rename it to Particle.
  2. For the Particle phase, select the following models:

    Group Box

    Model

    Enabled Models

    Laminar (Selected automatically)

    Flow (Selected automatically)

    Material

    Particle

    Enabled Models

    Constant Density (Selected automatically)

    Granular Temperature Transport (Selected automatically)

    Granular Pressure (Selected automatically)

  3. Click Close.
Specify the material properties for the gas phase.
  1. Edit the Phases > Air > Models > Gas > Air > Material Properties node and set the following properties:
    Node Property Setting
    Density > Constant Value 1.28 kg/m^3
    Dynamic Viscosity > Constant Value 1.7E-5 Pa-s
Specify the material properties for the particle phase.
  1. Edit the Phases > Particle > Models > Particle > Al > Material Properties node and set the following properties:
    Node Property Setting
    Density > Constant Value 2660.0 kg/m^3
    Particle Diameter > Constant Value 5.0E-4 m
Set the maximum solid fraction.
  1. Edit the Phases > Particle > Models > Granular Pressure node and set the Maximum Solid Fraction to 0.65.
Specify a reference value for the particle coefficient of restitution.
  1. Edit the Phases > Particle > Reference Values > Coefficient of restitution node and set the Value to 0.9.
  2. Save the simulation.
