Class
    Foam::fv::reactionDrivenPhaseChange
 
Description
    Model for mass-diffusion rate limited phase change between two phases.
 
    This model will transfer species out of a reacting phase at exactly the
    rate at which the reactions produce them. It facilitates a rough
    approximation to surface reactions for which certain species get consumed
    at the interface.
 
Usage
    Example usage:
    \verbatim
    phaseChange
    {
        type            reactionDrivenPhaseChange;
        libs            ("libmultiphaseEulerFvModels.so");
 
        // Note: Order is important. The reactions in the first phase define
        // the rate of phase change. If phase change also occurs as a result of
        // reactions in the second phase then a second model should be added
        // with the phases reversed.
        phases          (vapour particles);
 
        species         (TiO2);
 
        energySemiImplicit no;
    }
    \endverbatim
