Summary:In this study, novel longitudinal arc fins were proposed to increase the melting performance of phase change material in a latent heat thermal energy storage device. In order to optimize these innovative arc fins, various configurations of these fins were designed by changing the arc length, fin angle and eccentricity of the inner tube. In order to evaluate the performance of the new fins, five arrangements of traditional rectangular plate fins as well as a bare tube case were also numerically simulated. In all examined cases, the volume fraction of fins was considered constant and equal to 6.13%. Consequently, the best configuration of innovative fins was found by comparing melting characteristics of them with those of traditional rectangular plate fins. In addition, the effects of Al 2 O 3 nanoparticles on melting performance of some designed arc fins including the most efficient ones were evaluated. Results revealed that the best case was able to reduce the total melting time by 96.5% with respect to the bare tube and 67.7% with respect to 12 number of rectangular fins. In comparison with the pure PCM as the base case, addition of 2% and 5% nanoparticles can lead to time savings of 10.44% and 12.36%, respectively.
