Class
    Foam::Lagrangian::pressureWork
 
Description
    Model for pressure work. Subtracts the pressure-volume work associated with
    particle expansion from the particle energy, and adds it to the carrier
    energy. This model is needed to make (e.g.,) bubbles reduce in temperature
    as they expand.
 
Usage
    Example specification:
    \verbatim
    <LagrangianModelName>
    {
        type        pressureWork;
    }
    \endverbatim
