Detailed Description

Model for mass diffusion limited wall condensation between two phases on the surface of a number of wall patches. This model is based on an implementation described in Syrjanen, J., Hovi, V. (2023). The current implementation supports a single condensing specie.

Usage

Example usage:

wallCondensation
{
    type            wallCondensation;
    libs            ("libmultiphaseEulerFvModels.so");

    // Note: Order is important. This model is one-way. It turns vapour
    // into liquid. The phases should be specified in this order.
    phases          (steam water);

    // The specie that is condensing
    specie  H2O;

    energySemiImplicit yes;
    specieSemiImplicit no;

    saturationPressure
    {
        type            ArdenBuck;
    }
}

In addition to the above fvModel specification, wall patches on which condensation is to be calculated should have an alphatPhaseChangeWallFunction boundary condition applied to the turbulent thermal diffusivity field.
