Detailed Description

Evolves an electrical potential equation.

$\‍[ \grad \left( \sigma \grad V \right) \‍]$

where $ V $ is electrical potential and $\sigma$ is the electrical current.

To provide a Joule heating contribution according to:

Differential form of Joule heating - power per unit volume:

$\‍[ \frac{d(P)}{d(V)} = J \cdot E \‍]$

where $ J $ is the current density and $ E $ the electric field. If no magnetic field is present:

$\‍[ J = \sigma E \‍]$

The electric field given by

$\‍[ E = \grad V \‍]$

Therefore:

$\‍[ \frac{d(P)}{d(V)} = J \cdot E = (sigma E) \cdot E = (sigma \grad V) \cdot \grad V \‍]$

Usage

Minimal example by using constant/fvOptions:

jouleHeatingSource1
{
    // Mandatory entries (unmodifiable)
    type                 jouleHeatingSource;

    // Mandatory entries (runtime modifiable)
    anisotropicElectricalConductivity true;

    // Optional entries (runtime modifiable)
    T       <Tname>;

    // Conditional mandatory entries (runtime modifiable)

        // when anisotropicElectricalConductivity=true
        coordinateSystem
        {
            origin  (0 0 0);
            e1      (1 0 0);
            e3      (0 0 1);
        }

    // Conditional optional entries (runtime modifiable)

        // when anisotropicElectricalConductivity=false
        // Specify the conductivity as a function of temperature
        // If not supplied, this will be read from the time directory
        sigma           table
        (
            (273        1e5)
            (1000       1e5)
        );

        // when anisotropicElectricalConductivity=true
        sigma           (31900 63800 127600);
        //sigma           table
        //(
        //    (0      (0 0 0))
        //    (1000   (127600 127600 127600))
        //);

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: jouleHeatingSource	word	yes	-
`anisotropicElectricalConductivity`	Flag to indicate that if the electrical conductivity is anisotropic	bool	yes	-
`T`	Name of operand temperature field	word	no	T
`sigma`	Electrical conductivity as a function of temperature	table	no	-
`coordinateSystem`	User-specified coordinate system	coordSystem	no	-

The inherited entries are elaborated in:

fvOption.H

Note

anisotropicElectricalConductivity=true enables anisotropic (vectorial) electrical conductivity.
anisotropicElectricalConductivity=false enables isotropic (scalar) electrical conductivity.

The electrical conductivity can be specified using either:

If the sigma entry is present the electrical conductivity is specified as a function of temperature using a Function1 type.
If not present the sigma field will be read from file.
If the anisotropicElectricalConductivity flag is set to true, sigma should be specified as a vector quantity.
