摘要: A model based on the shrinking principle is developed to describe non-catalytic solid-fluid reactions when particles crack during process. Analytical and numerical solutions of governing equations under isothermal conditions are presented for some reaction orders, valid all geometries considered. Experimental results refining Fe-Si alloys by acid leaching suggested as an example data-fitting.
