This is accomplished through reactions involving intermediate copper and chlorine compounds, which act as catalysts that are recycled in the process. In this thesis, analytical and numerical solutions are developed to predict the behaviour of aqueous cupric chloride droplets in a solution undergoing spray-drying in the Cu-Cl cycle. The aqueous CuCl2 is present as a slurry within the cycle, which will later generate oxygen and hydrogen as a net result. The efficiency of the cycle can be increased by utilizing low-grade waste heat from any industrial source or nuclear power plant to assist in the drying process. There are many different methods employed in industry for drying of solutions. Each method has its own advantages and disadvantages, depending on the application and conditions. In this thesis, analytical correlations of heat and mass transfer are developed for the aqueous solution, subject to various drying conditions. The analysis is performed for moist air in contact with a sprayed aqueous solution of CuCl2(2H2O). Validation of the model is performed by comparisons with experimental results obtained from a Niro-spray dryer for CuCl2 and previous experimental and theoretical data for different fluids, on the basis of non-dimensional analysis.ennuclear-based hydrogen productioncopper-chlorine cycleCu-Cl cycleaqueous cupric chloride dropletsThesis
