Résumé

A limiting factor to the development of future performance aircraft is the operation of the thermal management system (TMS). Phase Change Materials (PCM) heat exchangers have been identified as a potential route to improving the effectiveness of the TMS, where the additional heat exchanger acts to reduce peak heat loads. In this paper, the effect of different fin geometries in the fluid layer, on the melting of PCM were studied for a PCM compact heat exchanger. Three different cases were compared, using three-dimensional CFD, over a range of mass flow rates, including a case without fins, continuous fins, and offset-strip fins. It was found that using fins led to a higher melt fraction and more uniform melting over the length of the heat exchanger. The continuous fin case was found to provide a middle ground between high liquid fraction and acceptable pressure drop. Furthermore, increasing the mass flow rate also led to a more uniform melting front,  although this was marginal for the finned cases.
