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.
