Hybrid thermal performance enhancement of a circular latent heat storage system by utilizing partially filled copper foam and Cu/GO nano-additives
Seyed Mohsen Hashem Zadeh,S.A.M. Mehryan,Mohammad Ghalambaz,Maryam Ghodrat,John Young,Ali J. Chamkha +5 more
TL;DR: In this article, a combination of copper foam and Cu/GO nano-additives is analyzed as the hybrid enhancement approach for thermal energy storage, and the results reveal that the charging power of the LHTES can be enhanced to about four times higher than the case of pure PCM at the cost of only a 3% reduction of the thermal storage's capacity.
