Modeling and analysis of CaBr{sub 2} hydrolysis.
The main focus of this paper is the modeling, simulation, and analysis of the CaBr{sub 2} hydrolysis reactor stage in the Calcium-Bromine thermochemical water splitting cycle for nuclear hydrogen production. One concept is to use a spray reactor of CaBr{sub 2} into steam. Droplet models were built up in a series of steps that consider various physical phenomena separately, including droplet flow, heat transfer, phase change, and reaction. Given the large heat reservoir contained in a pool of liquid CaBr{sub 2} that allows bubbles to rise easily, using a bubble column for the hydrolysis reaction appears to be a feasible and promising alternative to the spray reactor concept. The two limiting cases of bubble geometry, spherical and spherical-cap, are considered in the modeling. Results for both droplet and bubble modeling with COMSOL are presented together with recommendations for the path forward.
