    The case considered is 2-phase solids-laden turbulent vertical
    flow of air in a pipe, as studied experimentally by Tsuji et
    al [J.Fluid Mech, Vol.139, p417, 1984].
    The calculation is performed with the parabolic option.
    For comparison with data the calculation should be carried out
    until the flow is fully developed, i.e. 70 diameters downstream.
    The calculation may be made with the standard k-e model, or
    alternatively with the Chen-Wood or Mostafa-Mongia k-e variants
    which allow for gas turbulence modulation due to the presence
    of particles.
    The pipe Reynolds number is 3E4, the density ratio
    is 866, the particle mass-flow loading may be 1.0 or 2.1, and
    the particle diameter is 200 microns. The task is to calculate
    the fully-developed vertical velocity profiles for comparison
    with the measured profiles.
