Summary

The low thermal conductivity of paraffin-based phase change material (PCM) is a major obstacle to their utilization for domestic hot water storage. This issue is most often overcome by incorporating fins inside the PCM cavity to intensify the heat transfers. The impact of fins geometry on thermal performances has been widely investigated in literature, but the numerical validation is rarely realized with different experimental thermal loads and for different geometry of fins. This paper presents an experimental and numerical investigation of vertical fins inside a cavity filled with a paraffin-based PCM. Experiments are carried out with two different geometry of fins, for both thermal ramps and steps loads. Numerical modelling of the system is performed with an analytical approach in 2D. Experimental results show, for an equivalent volume of fins, better performances for the geometry with a number of fins multiplied by two and a thickness divided by two. Numerical results represent accurately the experimental heat flux and temperature for the two geometries and the various heat loads tested. As the model is validated and has a relatively fast computing time, future work could enables to identify the optimal geomtry of fins with optimization algorithms.
