AB The melting process of lauric acid in a square container heated from the top surface wasnumerically studied from an experimental case. Knowledge of this process is of special interestfor computationally efficient modeling systems, such as PCM-enhanced photovoltaic panels inhorizontal positions or energy storage using PCM embedded on flat surfaces. In these systems, thegeometric arrangement of the PCM hinders the fluid-phase movements through natural convection,which slows the melting process and can cause overheating in the fluid phase. Using Ansys FluentSoftware, three different approaches and two simulation methods, enthalpy-porosity and effectiveheat capacity, were developed for the numerical study. The results were compared with experimentalmeasurements in a successful evaluation of the accuracy of computational fluid dynamics simulations.It could be observed that the effective heat capacity method presented significant advantages over theenthalpy-porosity method, since similar accuracy results were obtained, and a lower computationalcost was required.
