Dispersed Multiphase Model Reference

The Dispersed Multiphase (DMP) model simulates dispersed phases in a Eulerian manner. The Dispersed Multiphase model combines aspects of both the Lagrangian Multiphase (LMP) model and the Eulerian Multiphase (EMP) models.

Boundary Settings

Applies to Velocity Inlet and Mass Flow Inlet only.

The Background method is useful in cases where the dispersed phase and the continuous background phase move at a similar velocity.

Velocity Specification

Controls how you define velocity on the boundary.


Method	Corresponding Value Nodes
Components Define all the components of the velocity vector.	Velocity Relative Velocity Sets the velocity vector in the chosen Coordinate System. When relative, the vector is defined within the reference frame applied to the boundary.
Magnitude + Direction Define the magnitude of the velocity vector, and take the direction based on the `Flow Direction Specification`.	Velocity Magnitude Relative Velocity Magnitude Sets the velocity magnitude by the selected Method. When relative, the magnitude is defined within the reference frame applied to the boundary.
Background This method is available in the Dispersed Multiphase model only. The velocity of the dispersed phase is taken from the background flow.	None.
