Experimental and Numerical Investigation of Phase Change Material Melting at Suboptimal Inclines

Abstract

Phase change materials (PCMs) are a key component to thermal energy storage solutions, which have the potential to hold a critical role in future energy storage. PCMs take advantage of large latent heat capacities as a method for storing thermal energy for later use. The research presented in this paper is part of an ongoing effort to document the melt behavior of lauric acid in an insulated rectangular container. This paper presents new experimental data of melting occurring at 180° and 135° incline. The data is processed to show the melt interface development and the melt fraction over the duration of the experiment. The results of the 135° incline experiment are compared to a numerical model and differences in results are examined.
