Class
    Foam::fv::viscousHeating
 
Description
    Applies the viscous heating redistribution source
    to the total energy equation.
 
    Note this term does not generate energy it is a conservative redistribution
    term, the enthalpy or internal energy source from viscous heating is a
    consequence of the kinetic energy loss, i.e. a transfer of energy from the
    kinetic energy part of the total energy to the thermal part.
 
Usage
    Example usage:
    \verbatim
    viscousHeating1
    {
        type        viscousHeating;
    }
    \endverbatim
