Droplet Breakup
Use the Droplet Breakup node to model the breakup of liquid droplets or parcels of droplets.
To use the Droplet Breakup feature, the following prerequisites must be met:
•
Newtonian or Newtonian, first order must be selected from the Formulation list in the physics interface Particle Release and Propagation section.
•
Either Specify particle diameter or Specify particle mass must be selected from the Particle size distribution list in the physics interface Additional Variables section.
•
Liquid droplets/bubbles must be selected from the Particle type list in the settings window for at least one Particle Properties node.
•
At least one instance of the Drag Force feature is needed. The valid selection for the Droplet Breakup feature comprises all domains where drag forces are defined.
The Kelvin-Helmholtz Breakup Model and Rayleigh-Taylor Breakup Model subnodes are available from the context menu (right-click the Droplet Breakup parent node) or from the Physics toolbar, Attributes menu. Only one copy of each subnode can be created at a time. The Kelvin-Helmholtz Breakup Model is created by default.
To model droplet breakup, unreleased secondary particles must be available. To ensure that all child droplets are released properly, a sufficiently large value must be specified for the Maximum number of secondary particles in the physics interface Particle Release and Propagation section.
