Abstract

Phase change materials and nanostructures are necessary to raise the efficiency of thermal energy (TE) storage systems, hence improving the efficiency of energy storage units. For this reason, the construction makes use of metal oxides and nanoscale metal particles. This work examined, using molecular dynamics modeling, the influence of nanoparticle (NP) size on the paraffin/O₂/Al₂O₃ hybrid heat sink performance. The results show that the thermal conductivity of the structure rose from 391.34 to 404.44 W/m.K as Al₂O₃ NP size rose. This resulted in lengthier NP aggregation from 6.95 to 7.02 ns. Moreover, changing the radius of NPs in a simulated construction would boost the heat flow from 333.99 to 368.05 W/m². Consequently, phase change materials and nanostructures improve the heat transfer (HT) and storage capacity of the system. Renewable energy systems, electronics cooling, and thermal management in industrial processes are just a few of the many disciplines where this technology might find use.

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
