Use the Kelvin-Helmholtz breakup model to account for the effect of Kelvin–Helmholtz instability on the breakup of liquid droplets. This causes small child droplets to be stripped away from larger droplets over time.
Enter a value or expression for the Kelvin-Helmholtz model coefficient BKH (dimensionless). The default value is
10.
If the Enable macroparticles check box is selected in the physics interface
Additional Variables section, enter a value or expression for the
Maximum number of particles released per breakup Nmax (dimensionless). The default is
10. This prevents an inordinate amount of child droplets from being released. If more child droplets than the maximum specified number would be released, then the multiplication factor of each particle is adjusted to compensate for the limited number of model particles.
The Density ρ (SI unit: kg/m
3) is taken
From material. For
User defined enter another value or expression. The default is
1 kg/m
3.
Enter the components of the Velocity field u (SI unit: m/s) based on space dimension. If another physics interface is present which computes the velocity field then this can be selected from the list.
