ABSTRACT Latent heat thermal energy storage (LHTES) systems using phase change material (PCM) could have lower heat transfer rates during charging/discharging processes due to its low inherence of the thermal conductivity. In this study, heat transfer enhancement using internal longitudinal fins employing PCM first and nanoPCM secondly in a large triplex tube heat exchanger (TTHX) was investigated by Fluent 15 software numerically. The results showed the thermal conductivity of pure PCM (0.2 W/m.K) could be enhanced to 25% by dispersing 10% alumina (Al2O3) as a nanoparticle. However, the melting time is reduced to 12% as compared with the PCM only therefore, a longitudinal fins-nanoPCM technique achieved a complete PCM melting shortly (218 minutes). Consequently, the simulation results have been validated and illustrated a good agreement with the PCM and nanoPCM experimentally. |
