Detailed Description

A heat transfer model for simulation of sub-cooled nucleate wall boiling on the surface of a third phase with runtime selectable sub-models. This model should be applied to the liquid side of the liquid-third-phase interface.

Usage
Settings below are very similar to that of the alphatWallBoilingWallFunction (refer to this model's documentation for further details). The only differences are that an underlying heat transfer model is also required, and the phase-identifying entries are somewhat different; the liquid and vapour phases must be specified explicitly.

A corresponding heat transfer model on the other side of the liquid-third-phase interface is required by this model, and is also shown below.

Example usage:

    type            wallBoiling;

    liquidPhase     liquid;
    vapourPhase     gas;

    heatTransferModel
    {
        type            Gunn;
    }

    partitioningModel
    {
        type            Lavieville; // phaseFraction, linear, cosine
        alphaCrit       0.2;
    }
    nucleationSiteModel
    {
        type            LemmertChawla; // KocamustafaogullariIshii
