Performance Evaluation of Coupled Thermal Enhancement through Novel Wire-Wound Fins Design and Graphene Nano-Platelets in Shell-and-Tube Latent Heat Storage System

Technological development in latent heat storage (LHS) systems is essential for energy security and management both renewable non-renewable sources. In this article, numerical analyses on a shell-and-tube-based LHS system with coupled thermal enhancement through extended fins nano-additives are conducted to propose optimal combinations guaranteed higher discharging rate, enthalpy capacity distribution. Transient simulations of fourteen scenarios varied investigated three-dimensional computational models. The shell-and-tube includes paraffin as phase change material (PCM), longitudinal, radial wire-wound graphene nano-platelets (GNP) nano-additives, respectively. have demonstrated better effectiveness than nano-additives. For instance, the durations shortened by 88.76%, 95.13% 96.44% compared 39.33% 2.5% GNP. combined strengths indicated further neutralising insulative resistance stratification paraffin. However, increase volume fraction from 1% 3% 5% rather detrimental total capacity. Hence, novel designed base GNP proposed candidates owing their significantly transfer potentials. configuration can retrieve 11.15 MJ 1.08 h 44.5 conventional without fins. addition, prolonged service life zero maintenance flexible scalability meet medium large-scale demands.
