The case considered is the acceleration of particles by a uniform
flowing gas stream. The flow is steady, one dimensional and it is
assumed that there is no particle interaction. The analytical
solution for this case has been given by Morsi and Alexander (JFM,
Vol.55, p193, 1972). The free-stream velocity is not affected by
the particles owing to their very low concentration. The density
ratio is taken as 2000, the particle diameter as 500 microns, and
the particle Reynolds number as 3,000. The calculation may be
performed in the x-, y- or z-direction with phase 1 as carrier
(gas) and phase 2 as dispersed (solid) or vice versa (CONPHS=2).
