Heat transfer enhancement in phase change materials (PCMs) by metal foams and cascaded thermal energy storage [PDF]

open access: yes
Low heat transfer performance has been the main problem restricting the use of Phase Change Materials (PCMs) in situations requiring rapid energy release or storage. Three innovative solutions are studied in this Thesis to improve heat transfer in PCMs.
