“…Various researchers illustrate the use of PCMs and the parameters involved in developing phase-change materials' performance. Castell (2015) illustrates that, from the primary model to a model developed on the renewable energy transition process, storage of energy can be easily possible. This storage of energy can be easily achieved at a higher rate by PCMs.…”

The energy storage application plays a vital role in the utilization of the solar energy technologies. There are various types of the energy storage applications are available in the todays world. Phase change materials (PCMs) are suitable for various solar energy systems for prolonged heat energy retaining, as solar radiation is sporadic. This literature review presents the application of the PCM in solar thermal power plants, solar desalination, solar cooker, solar air heater, and solar water heater. Even though the availability and cost of PCMs are complex and high, the PCMs are used in most solar energy methods due to their significant technical parameters improvisation. This review's detailed findings paved the way for future recommendations and methods for the investigators to carry work for further system developments.

“…Phase-change materials (PCMs) are widely used in energy storage applications because of their high latent heat [1][2][3]. The temperature and density of PCMs remain nearly constant during the phase change [4], which makes them suitable for a variety of thermal management applications including heat exchangers [1,5], electronic cooling [6,7], building applications [8], solar energy storage [9], and spacecraft thermal control [10,11]. In these applications, PCMs are often encapsulated in a variety of enclosures (e.g., cylinders, spheres, annular cavities, etc.)…”

We numerically investigate the melting and solidi?cation behavior of phase change materials encapsulated in a small-radii cylinder subjected to a cyclic convective boundary condition (square wave). Initially, we explore the effect of the Stefan and Biot numbers on the non-dimensionalized time required (i.e. reference Fourier number Tref ) for a PCM initially held at Tcold to melt and reach the cross?ow temperature Thot. The increase in either Stefan or Biot number decreases Tref and can be predicted accurately using a correlation developed in this work. The variations of the PCM melt fraction, surface temperature, and heat transfer rate as a function of Fourier number are reported and analyzed for the above process. We further study the effect of the cyclic Fourier number on the periodic melting and freezing process. The melting or freezing front initiates at the outer periphery of the PCM and propagates towards the center. At higher frequencies, multiple two-phase interfaces are generated (propagating inward), and higher overall heat transfer is achieved as the surface temperature oscillates in the vicinity of the melting temperature, which increases the effective temperature difference driving the convective heat transfer.

“…Heat exchanger design is often done with the assistance of mathematical relationships such as the ε-NTU methods. The ε-NTU method, however, assumes two moving fluids and so must be adjusted for situations involving heat transfer to a stationary material undergoing phase change [5]. In order to develop an ε-NTU method for PCM-based heat exchanger, or possibly an entire new method, additional experimental results obtained on various PCM-based heat exchanger geometries under various conditions must be performed.…”
