    PUFoam

Description
    Solver using "compressibleInterFoam" as the basis to simulate the expansion
    of Polyurethane foam (PU). It includes Quadrature Method of Moments (QMOM)
    to solve a 'Population Balance Equation' (PBE) determining the bubble size
    distribution inside PU foams.

    Kinetics of the reactions including gelling, blowing and evaporation of
    the physical blowing agent are incorporated into the solver.

    Finally, the kinetics and PBE has been coupled to describe the time
    evolution of foaming process.
