    NUMERICAL BENCHMARK PROBLEM 1.1:  CONVERGENT-DIVERGENT NOZZLE
    Two fluids flow through a convergent-divergent nozzle. The
    lighter one is a compressible gas; the second one, which is
    in much smaller volumetric concentration, is incompressible.
    The density ratio is such that the pressure gradients which
    accelerate the gas have less effect upon the motion of the
    heavier fluid; but the latter is nevertheless also
    accelerated by the drag exerted upon it by the gas.

    The task is to predict the distributions of pressure, volume
    fraction and velocity along the duct, under various
    conditions.
