“…The graphics plotted show the degree of agreement between experimental results and simulations. To quantify the difference between experimental data and simulated results, the Relative Maximum Error [17] and an average error were used as indicated in Equations. (5) and (6): The first is a comparison between experimental and numerical results of a brick without PCM.…”

The integration of a PCM layer into an external building wall diminished the amplitude of the instantaneous heat flux through the wall. The types of PCM, its location in the wall and its amount, have been studied in this paper. A two-dimensional transient heat transfer model has been developed and solved numerically using the commercial Computational Fluid Dynamics (CFD) package Fluent. The numerical results have been verified and validated with an experimental model. The considered model consists of usual brick with square holes used as construction materials for residential buildings in Algeria, some of these square holes are filled with PCM. The results showed that the PCM introduced in square holes can improves considerably the thermal inertia of brick and a combination of the types of m PCM, its location in the wall and its amount, is very important for improve reduction of heat gain before it reaches the indoor space.

“…Due to the complexity of numerically simulating the flow and heat transfer in porous mediums (storage tank filled with encapsulated PCMs), there are only a couple of research papers investigated the energy delivery and extraction using comprehensive 3D CFD study. Zukowski [157] performed a 3D comprehensive simulation for latent storage system incorporated with cubic encapsulated PCM using an inhouse code, and the interpolating cubic spline function method was applied to determine the value of specific heat capacity of PCM in each time step, which can automatically track the melting and solidification of PCM capsules. MacPhee and Dincer [158] presented what appears to be the first CFD analysis for spherical encapsulated PCM inside a latent thermal storage tank.…”

h i g h l i g h t sThermal storage for solar thermal power using phase change materials is reviewed. Various phase change materials and manufacturing techniques are surveyed. Mathematical modeling and simulations to latent heat energy storage is reviewed. Integration of a PCM-based TES unit into a power generation system is discussed. Cost analysis of thermocline latent heat thermal storage systems is reviewed. Keywords: Concentrated solar power (CSP) Thermal energy storage (TES) Phase change material (PCM) Latent heat a b s t r a c tThe objective of this paper is to review the recent technologies of thermal energy storage (TES) using phase change materials (PCM) for various applications, particularly concentrated solar thermal power (CSP) generation systems. Five issues of the technology will be discussed based on a survey to the state-of-the-art development and understandings. The first part is about various phase change materials (PCM) in thermal storage applications and recent development of PCM encapsulation technologies. The second is the current status of research and application of latent heat storage systems in CSP plants. The third is the mathematical modeling and numerical simulations to the phenomenon of latent heat thermal storage. The fourth is about the issues of integration of a PCM-based TES unit into a power generation system and the operation. The last part is a discussion about the cost issues and comparison between sensible and latent heat TES systems. The surveyed information will be very helpful to researchers and engineers in energy storage industry and particularly solar thermal power industry.

“…Besides, the above models do not take into account the heat capacity dependence with temperature. Furthermore, Zukowski [28] studied the charge and discharge characteristics of a thermal energy storage (TES) prototype device -a Plexiglas casing, light steel nets and PCM enclosed in polyethylene film bags-and developed a computational model in three dimensions. In the computational model he avoided working with the location of the solid-liquid interface using an apparent specific heat which was dependent on temperature.…”
