Interests: low GWP refrigerants; PCMs; nanofluids; thermophysical properties; HVACR applications
We are inviting submissions to a Special Issue of Energies on the subject area of “Phase Change Materials (PCMs) for Heat Storage in Building Applications”. PCMs offer important opportunities to increase the thermal efficiency of buildings by reducing the peak power for heating and cooling, allowing better management of shift peak in heating and cooling or optimizing the coupling with renewable energies.
This Special Issue will deal with formulations of PCMs, their properties and their applications in both heating and cooling plants and building construction materials. Topics of interest for publication include, but are not limited to the following:
- PCMs materials, also with nanostructures (NEPCMs)
- Thermal and physical properties of PCMs and NEPCMs
- Heat transfer
- Technologies to apply PCMs (e.g., microencapsulation, embedding in construction materials, etc.)
- Applications of PCMs in buildings (construction materials (passive), thermally activated constructions, glazing and shading devices, combined with ventilation and air-conditioning)
- Heat storage and renewable energy systems
- Energy analysis

Abstract: This work numerically investigates the melting of a phase change material (PCM) embedded into metallic porous foam in a straight duct where forced convection prevails. The thermal lattice Boltzmann method (TLBM) with three distribution functions is adopted to simulate the unsteady convective flow using the Brinkman-Forchheimer-Darcy (BFD) model. In this method, the fluid consists of a particles' number that stream and interact in certain specified directions depending on the lattice structure. The two-equation energy model is used here to handle the local thermal non-equilibrium (LTNE) that occurs between fluid and solid phases. The flow is unsteady, incompressible, and 2D. In addition, the fluid-saturated porous medium is considered homogeneous, isotropic, non-deformable, and in LTNE with the fluid. Thereby, such a problem is modeled by considering the generalized dimensionless Navier-Stokes equations for a porous media at the representative element volume (REV). The problem formulation is completed by appropriate boundary and initial conditions and by the enthalpy-porosity model to compute the PCM liquid fraction. Note that the solid PCM has a melting temperature (Tm

Abstract: Phase change materials (PCMs) can absorb, store and release large amount of energy without any significant temperature change due to high latent heat. This feature allows PCMs to become an attractive element for energy storage systems. PCM have been used widely on the interior or exterior walls of the building application to decrease the energy consumption during heating and cooling periods. Meanwhile, ground source heat pump (GSHP) gained its popularity due to the advantages of greenhouse gas (GHG) reduction. However; GSHP system has some limitations in terms of cost, performance and drilling space. This study presents an innovative concept of energy piles, as a PCMs tube containers were used inside a lab-scaled building foundation pile. The investigation was conducted experimentally and numerically on three identical piles with different amounts of PCMs. Furthermore, a parametric study was conducted to study the effect of the working fluid flow rate on the amount of energy stored and released at each sample. An extensive CFD model was developed and compared with the experimental data. The numerical results were in good agreement with the experimental data. The results revealed that increases in PCMs volume inside the pile enhance storing capacity, concrete thermal response and storage efficiency of the piles. Although, increasing the flow rate increased the amount of energy stored and released, the percentage increase on the energy stored and released was insignificant compared to the percentage increase on the flow rate.
