@article { , title = {Evaluation of thermal energy dynamics in a compacted high-conductivity phase-change material}, abstract = {This study evaluates the concept of developing a nondeform phase-change energy storage material possessing higher thermal conductivity and energy storage density through a pressure compaction process. The theoretical and experimental investigations have shown that the technique is able to reduce porosity and increase conductivity and energy storage density of a composite material. Even though there was some measure of plastoelasticity due to decompression, the average porosity was reduced from 62 to 23.8\% at a relatively low compaction pressure of 2.8 MPa without any structural damage to the tested sample. The mean energy storage density increased by 97\%, and the effective thermal conductivity also increased by 25 times, despite a 10\% reduction in its latent heat capacity. There is, however, the need for further development toward minimizing the effect of decompression and achieving stronger energy storage tablets at a relatively low compaction force.}, doi = {10.2514/1.T3911}, eissn = {1533-6808}, issn = {0887-8722}, issue = {2}, journal = {Journal of Thermophysics and Heat Transfer}, publicationstatus = {Published}, publisher = {American Institute of Aeronautics and Astronautics}, url = {https://nottingham-repository.worktribe.com/output/748782}, volume = {29}, keyword = {Phase change material, Non-deformed, Tablet, Energy storage density}, year = {2015}, author = {Darkwa, Jo and Su, O. and Zhou, T.} }
