Study on heat-storage and release characteristics of multi-cavity-structured phase-change microcapsules

Based on the solutions of apparent heat capacity method for phase-change problems, numerical simulations were performed to study the heat-storage and release processes for the multi-cavity-structured phase-change microcapsules in this paper. Moreover, the influence of the cavity structures of the phase-change microcapsules on the heat-storage and release capacity was analyzed. The results show that the rate of heat-storage and release will be accelerated by increasing the number of cavities in microcapsules, and cavity interlayer is the key factor to enhance the heat transfer.
