Detailed 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.

Reference:

    Brun, P. T., Damiano, A., Rieu, P., Balestra, G., & Gallaire, F. (2015).
    Rayleigh-Taylor instability under an inclined plane.
    Physics of Fluids (1994-present), 27(8), 084107.

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