Mathematical Modeling of Noncatalytic Fluid-Solid Reactions—Generalized Mathematical Modeling of Fluid-Solid Non-Catalytic Reactions Using Finite Volume Method: Nonisothermal Analysis—

Abstract

A mathematical model has been developed based on the nonisothermal Sharp Interface Model (SIM) for Fluid-Solid Non-Catalytic (FSNC) reactions for nonporous solid reactants. Fully transient analysis has been carried out for particles with both constant and varying sizes incorporating powerlaw kinetics. The Finite Volume Method (FVM) has been employed for numerical solution of the moving boundary problem. Its suitability in such applications has been established. The effects of various model parameters on the reaction characteristics have been studied. The phenomena of instabilities have also been analyzed.
