Convective heat and entropy transfer in multiphase flows with droplets and particles
FY 2014-15
Summary
Driven by the dangers of climate change, researchers around the world are striving to develop sustainable energy solutions that reduce greenhouse gas emissions. This research program investigates multiphase flows with droplets and particles, particularly as they arise in clean energy systems, such as thermochemical hydrogen production and other applications. Hydrogen is a clean energy carrier and potentially major solution to climate change. In the thermochemical copper-chlorine (Cu-Cl) cycle of hydrogen production, water is decomposed into hydrogen and oxygen, through a sequence of processes that involve phase change heat transfer, droplets and particles. This research program conducts numerical and experimental studies to improve the understanding of these multiphase processes. Better understanding of multiphase flows, in these and other applications, will lead to improvements in system performance and energy efficiency.More specifically, the multiphase processes include drying of aqueous solution droplets, and heat recovery from solidified particles of molten salt. An aqueous solution of copper II chloride exits an electrochemical cell and enters a spray dryer, where it is dried and solidified to produce solid feed for a subsequent hydrolysis process. This research would investigate the coupled heat and mass transfer in the aqueous solution droplets. No previous data or knowledge is available for the complex morphology of the copper II chloride crystal formation during water removal. Another key process in the Cu-Cl cycle is heat recovery from molten CuCl at 500 C, which exits an oxy-decomposition reactor. Unfortunately, no demonstrated process exists at this time in the world to effectively recover heat from molten CuCl that solidifies as it cools when leaving the oxy-decomposition reactor. This research examines the detailed processes of heat and entropy transfer of molten salt droplets and solidification, in order to improve the fluids engineering equipment performance.
