Abstract: The dispersion of spherical particles dropped into an initially quiescent bath and the effect of dissolution upon this dispersion is examined numerically. Some of the factors which affect the extent of penetration, spread and general pattern of dispersion of dissolving particles are discussed. Computations are based upon a pseudo two dimensional finite volume, Eulerian-Eulerian, multiphase model which couples flow of the solid and liquid phases. It is found that dissolution has a significant effect upon the dispersion of the particles for solid/liquid density ratios greater than one. However, if the solids are neutrally buoyant, little if any modification to the distribution of the solids due to dissolution is found.
