This paper presents the dispersion of buoyant solid spherical particles injected through a round vertical liquid water impinging jet onto a cylindrical bath. The air is entrained in the form of bubbles and interacts with the injected particles. The primary flow behaviour is validated against experimental LDV (Laser Doppler Velocimetry) data (Khan, 2003). Taking the advantage of axisymmetric domain, computational models of the primary and particulate flow (discrete phase model, DPM) are solved by finite volume method, FVM, using a commercial CFD software FLUENT. The detail experimental study for similar cases is very difficult in terms of measuring the particle velocity and interaction with the liquid.
