Detailed Description

Applies a viscous dissipation energy source to the energy equation.

Sources applied to either of the below, if exist:

  e         | Internal energy                            [m2/s2]
  h         | Enthalphy                                  [m2/s2]
  field     | User-specified field

Required fields:

  U         | Velocity                                   [m/s]
  rho       | Fluid density (for compressible flows)     [kg/m3]

Usage

Minimal example by using constant/fvOptions:

viscousDissipation1
{
    // Mandatory entries (unmodifiable)
    type                 viscousDissipation;

    // Optional entries (unmodifiable)
    fields           (<fieldName>);
    U                <UName>;
    rho              <rhoName>;

    // Conditional optional entries (unmodifiable)

        // when rho=rhoInf
        rhoInf       1000;

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

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: viscousDissipation	word	yes	-
`fields`	Name of operand (energy) field	word	no	-
`U`	Name of operand velocity field	word	no	U
`rho`	Name of operand density field	word	no	none
`rhoInf`	Value of fluid density	scalar	cndtnl	0

The inherited entries are elaborated in:

fvOption.H

Note

The entry fields accepts only a single field name.
The sources are applied onto the entire computational domain.
rho=rhoInf sets a zero-density for single phase flows.
Not applicable to multiphase flows.
