1. Introduction
Heat transfer during melting and/or freezing of a phase change material (PCM) has attracted considerable attention over the past several decades due to its relevance to many technological applications such as latent-heat energy storage systems, solar energy systems, casting and crystal growth processes [1,2]. Divers papers have examined various aspects of melting and freezing phenomena both from the fundamental as well as applications point of view [3,4]. The non-linearity of the governing energy equation and a wide variety of geometric and thermal boundary conditions provide a fertile ground for challenging basic research problems [5,6]. Also, numerous industrial applications in diverse industries provide the necessary incentive for engineering research and development [7,8]. Time-dependent boundary conditions, under some conditions can lead to interesting and unique multiple moving boundaries as well. Although a number of experimental and numerical studies have been devoted to convection dominated melting of a PCM for various geometric configurations, particular attention is given to melting in a horizontal cylinder as a model for thermal energy storage system [9–16]. A number of numerical and analytical studies have been performed in an attempt to model the melting phenomenon in a horizontal cylinder based on the Boussinesq approximation [17–23]. Saitoh and Hirose [17] presented experimental results which show convexed solid-liquid interface at the bottom of the unmelted solid during the melting process. Rieger et al. [18], Ho and Viskanta [19] and Yoo and Ro [20] investigated experimentally the evolution of the solid-liquid interface during melting of a PCM contained in a horizontal cylinder. They showed concaved interface numerically and experimentally. Prasad and Sengupta [21]studied numerically the unconstrained melting of a PCM inside an isothermal horizontal tube. The model evaluated the irregular, temporal shape of the solid–liquid interface, the downward traveling motion of solid PCM due to density difference, and natural convection in the liquid phase.
