Detailed Description

Variable Documentation

cdrift

cdrift

Flux factor parameter. In case of drift flux, factor of the local flux compared to the global max flux.

idrift

idrift

drift velocity model

• 0: drift model disable
• 1: field inner_drift_velocity_flux is used Deshpande's model
• 2: field drift_velocity is used User-defined drift velocity field

kdrift

kdrift

Turbulent like diffusion effect (m2/s). In case of drift velocity, factor of a volume fraction gradient

mu1

mu1

reference molecular viscosity of fluid 1 (kg/(m s))

mu2

mu2

reference molecular viscosity of fluid 2 (kg/(m s))

rho1

rho1

reference density of fluid 1 (kg/m3). By convention, liquid phase for cavitation model.

rho2

rho2

reference density of fluid 2 (kg/m3). By convention, gas phase for cavitation model.

sigma_s

sigma_s

reference surface tension (N/m)

vof_model

vof_model

Volume of Fluid model - sum of masks defining VoF model and submodels. See defined masks in Masks used to specify Volume of Fluid models.
