Detailed Description

Blending method based on smooth hyperbolic functions. Supports the full range of phase fraction space. E.g., from droplets in air, through a segregated regime, to bubbly flow.

This method requires a volume fraction at which the phase is considered to become continuous, and a range of volume fraction over which this occurs, to be specified for both phases.

Alternatively, the volume fraction can be omitted or replaced with the keyword "none" to represent a phase which cannot become continuous. E.g., a particulate phase.
