Numerical Treatment of Oxide Particle Dissolution in Multicomponent Slags with Local Gibbs Energy Minimization

Herein, a diffusion model for the dissolution of oxide particles in multicomponent slag systems is developed. It assumed this that sharp-interface separates solid particle from liquid slag. Minimization Gibbs energy provides conditions at interface. The differential equations are solved numerically via finite-difference scheme. indicated parameter studies controlled kinetics may result strongly different profiles depending on initial conditions. demonstrated rate-controlling dissipative process components cases where earlier investigations claimed coupled diffusion-reaction charge kinetics. Eventually, numerical results compared to data obtained high-temperature laser scanning confocal microscopy (HT-LSCM) experiments.
