Class

|
Foam::blendingMethods::hyperbolic
|
|
|
|
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.
