If the libs entry is not provided and the name of the library containing the
functionObject, fvModel or fvConstraint corresponds to the type specified the
corresponding library is automatically loaded, e.g. to apply the
VoFTurbulenceDamping fvModel to an incompressibleVoF simulation the following
will load the libVoFTurbulenceDamping.so library automatically and instantiate
the fvModel:
turbulenceDamping
{
type VoFTurbulenceDamping;
delta 1e-4;

Description
|
|
Brun dripping film to cloud ejection transfer model
|
|
|
|
If the film thickness exceeds the critical value needed to generate one or
|
|
more drops, the equivalent mass is removed from the film. The critical film
|
|
thickness is calculated from the Rayleigh-Taylor stability analysis of film
|
|
flow on an inclined plane by Brun et.al.

|
|
|
|
The diameter of the drops formed are obtained from the local capillary
|
|
length multiplied by the \c dCoeff coefficient which defaults to 3.3.
