摘要

This paper examines the transient chemical decomposition of solid particles in a multiphase flow consisting of molten and gaseous phases at high temperature and low Reynolds number. The mass, energy, momentum and chemical reaction equations are solved for a particle immersed in a viscous flow of uniform properties. Numerical solutions are obtained and the results are validated with experimental data of samples involving the chemical decomposition of the mixture of CuO and CuCl_2 particles in a molten salt. The analysis provides new insight into the implications of the rate of reaction vs. heat and mass transfer in a complex gas-solid-molten salt multiphase reacting system, as well as the impact on hydrogen yield in the thermochemical copper-chlorine (Cu-Cl) cycle of hydrogen generation.
