KINETICS OF DISSOLUTION OF A POLYDISPERSE SYSTEM OF SPHERICAL-PARTICLES INTO MOLTEN-METAL .1. ONE-ADDED PORTIONS

The paper deals with kinetics of dissolution of spherical particles wi th different radius and discrete distribution of mass fractions, belon ging to the certain radius. Kinetic equations taking in account the ch ange of the Reynolds hydrodynamic criterion during dissolution and con sequently the transition from one type of hydrodynamic regime of flow to another were derived. Dissolution is assumed to be controlled by di ffusion. Based on theoretical considerations a computer program was de veloped. The graphic output of this program demonstrates the time depe ndence of quantities characterizing the dissolution process.
