However, their per formance is often limited by slow melting/charging rates, which motivates the search for enhanced heat transfer designs. This study investigates the melting behavior of RT-82 phase change material (PCM) using novel lotus shaped fins combined with copper metal foam and conductive graphene nanoparticles and carbon nanotubes. A two-dimensional enthalpy–porosity model in ANSYS Fluent was developed to simulate the charging/melting process, capturing non-thermal equilibrium between the foam and PCM/nano-PCM. In this study, effects of fin geometry, nanoparticle concentration, and foam porosity on melting dynamics and cost-performance trade-offs were investigated. Results showed that natural convection accelerated melting by ~12% compared to conduction-only scenarios. Optimized lotus-shaped fins with higher fin density (T3F4 and T3F10) achieved up to 63% faster melting relative to sparse configurations. Graphene nanoparticles improved thermal conductivity, with a 6% volume fraction, by reducing melting time by ~6.9%, while their combination with 75% porosity foam achieved a maximum reduction in the melting time of ~51% compared to pure PCM. Cost-performance analysis identified T3F4 as the most balanced design, offering rapid thermal response without excessive mate rial costs, while moderate-density designs like T3S6 provided economical alternatives with acceptable perfor mance. These results highlight the performance enhancement that can be achieved by integrating bio-inspired fins, nanoparticles, and foams, into compact and efficient LHTES for solar heating, building thermal manage ment, and industrial waste-heat recovery applications.Eficiencia energética y uso racional de la energíaEnergías alternativas28 páginasapplication/pdfengInternational Journal of Heat and Mass Transferhttp://creativecommons.org/licenses/by/4.0/https://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccessAtribución 4.0 Internacional (CC BY 4.0)http://purl.org/coar/access_right/c_abf2620 - Ingeniería y operaciones afines::621 - Física aplicadaNature-inspired shaped finsPhase change materialMelting/chargingSolidification/dischargingThermal energy storagePerformance enhancementAlmacenamiento de energía térmicaThermal energy storageEnergía renovableRenewable energyTransferencia de calorHeat transfer2.
