Setting Up the Injector

You set up an injector to introduce the particles of the dispersed Lagrangian phase into the solution domain. The injector defines the initial state of the particles.

To set up the injector:

  1. Right-click the Injectors node and select New.
  2. Select the Injectors > Injector 1 node and set Type to Part Injector.


  3. Set Inputs to Regions > Default Fluid > Boundaries > inlet.


  4. Click OK.
  5. Set Lagrangian Phase to Phase 1.


The Number of Points property is 0 until the injection points are calculated during solution initialization. Specify the conditions and values of the injector to define the particles.

  1. Open the Injectors > Injector 1 node.


  2. Edit the following nodes and set the appropriate properties:
    Node Property Setting
    Conditions > Flow Rate Specification Method Volume Flow Rate
    Flow Rate Distribution Method Per Injector

    This signifies that the volume flow rate applies to the whole injector, rather than per injection point.

    Velocity Specification Method Magnitude + Direction
    Values > Volume Flow Rate Value 6.4516E-7 m3/s
    Particle Diameter Value 4.0E-5 m
    Velocity Magnitude Value 10 m/s
  3. Save the simulation.
