Detailed Description

template<class CloudType>
class Foam::LiquidEvapFuchsKnudsen< CloudType >

Liquid evaporation/condensation model for solution of liquid and solid.

This model takes into account the Fuchs-Knudsen number correction, the modified Raoult's law is used to obtain the concenration of the evapora ble component on the surface and the activity coefficient is used. The correction Kelvin effect is used.
