NUMERICAL ANALYSIS ON MELTING IN A CYLINDRICAL HEAT STORAGE CAPSULE
The present paper describes the application of computational fluid-dynamics (CFD) for the analysis of melting process in a cylindrical enclosure heated from the side. The 2D model is based on a finite-volume numerical procedure that adopts the enthalpy method to take in account the phase change phenomenon. The time-dependent simulations show the melting phase front and melting fraction of the PCM and incorporate the fluid flow in the liquid phase. The obtained temperature profiles are compared to a set of experimental data available on a web site for public access. The results show that during the melting process natural convection within the PCM has non negligible effects on the behavior of the system. The paper also discusses the effects on the phase-change processes of the main operating conditions, including inlet temperature and mass flow rate of the heat transfer fluid.
