Heat Transfer-Based on Nano-particles for Thermal Energy Storage in Phase Change Material

Abstract: This study investigates the enhancement of thermal energy storage performance in phase change materials (PCMs) through the integration of nanoparticles, focusing on nano-enhanced PCMs (NEPCMs). A finite volume numerical model is developed to simulate heat transfer and fluid dynamics during the melting process within a cylindrical enclosure. The governing equations of mass, momentum, and energy are discretized and non-dimensionalized to evaluate the effects of nanoparticle concentration, size, and distribution on heat transfer efficiency and thermodynamic stability. Aluminum oxide (Al O ) is used as the nanoparticle additive, with simulation results highlighting the relationship between enthalpy, energy, and velocity. The results demonstrate that nanoparticle incorporation significantly improves thermal conductivity, stabilizes flow during phase transition, and enhances overall system performance. These findings offer crucial insights into the design and optimization of solar thermal energy storage systems using NEPCMs for sustainable energy applications.
