Evolves a passive scalar transport equation within one phase of a multiphase simulation. The scalar is considered to be a phase-intensive property; i.e., its value represents an amount per-unit of the phase. In addition to the scalar, the function also writes out the product of the volume fraction and the scalar, as this provides a phase-extensive field which is often more convenient to post-process.

Detailed Description

Evolves a passive scalar transport equation within one phase of a multiphase simulation. The scalar is considered to be a phase-intensive property; i.e., its value represents an amount per-unit of the phase. In addition to the scalar, the function also writes out the product of the volume fraction and the scalar, as this provides a phase-extensive field which is often more convenient to post-process.

Most entries are the same as for the scalarTransport function. Refer to its documentation for details. Entries specific to this function are detailed below. Note that the phase-name will be determined by stripping the extension from the supplied field name.

If the solver does not provide an alphaPhi flux, or that flux is for some reason unreliable, then the solveAlphaPhi switch can be used to make this function solve a pressure-like equation from which alphaPhi is recovered.

Usage

Property	Description	Req'd?	Default
`alpha`	Name of the volume-fraction field	no	alpha.<phase-name>
`alphaPhi`	Name of the phase-flux field	no	alphaPhi.<phase-name>
`solveAlphaPhi`	Solve for the alphaPhi flux, rather than looking it up	no	false
`p`	Name of the pressure field	no	p
`residualAlpha`	Small volume fraction used to stabilise the solution	no	rootSmall
`writeAlphaField`	Also write out alpha multiplied by the field	no	true

Example specification for incompressibleVoF:

    phaseScalarTransport1
    {
        type            phaseScalarTransport;
        libs            ("libsolverFunctionObjects.so");

        field           s.water;
    }

Example specification for multiphaseEuler:

    phaseScalarTransport1
    {
        type            phaseScalarTransport;
        libs            ("libsolverFunctionObjects.so");

        field           s.water;
        alphaPhi        alphaRhoPhi.water;
        rho             rho.water;
