Convective heat and entropy transfer in multiphase flows with droplets and particles

在气候变化危险的推动下，世界各地的研究人员正在努力开发减少温室气体排放的可持续能源解决方案。本研究项目研究液滴和颗粒的多相流动，特别是在清洁能源系统中出现的多相流动，如热化学制氢和其他应用。氢是一种清洁能源载体，也是解决气候变化的潜在主要方案。在产氢的热化学铜-氯（Cu-Cl）循环中，水通过一系列涉及相变传热、液滴和颗粒的过程分解为氢和氧。本研究计划进行数值和实验研究，以提高对这些多相过程的理解。更好地了解多相流，在这些和其他应用中，将导致系统性能和能源效率的改进。

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.
