Special Issue Information

Dear Colleagues,

The Special Issue entitled "Phase Change Materials and Building Systems Dynamics" aims to provide an integrated approach to the interactions and modeling between phase change materials embedded in the passive and active engineering systems dynamics of the built environment towards economic growth decoupling from resource depletion and environmental degradation in different levels.

This Special Issue belongs to the Section "Sustainable Materials".

Dear Colleagues,

Phase change materials and their integration in the built environment, both in passive and active systems, are one of the promising methods to provide latent storage towards peak load reduction and/or energy savings optimization. Since engineering systems interact with their environment, knowledge of their impacts is always of utmost importance toward the transition to sustainable living. The linkage between the sustainable life circles of phase change materials and the optimal modeling of interaction dynamics, the cost-effectiveness, and the strategic mechanisms to support the guidance of the framework of the system are of paramount interest, especially in recent years that technosphere and ecosphere boundaries urgently require a balance. In addition, many efforts are directed on, as well as debating, decoupling economic growth from resource depletion and environmental degradation at different levels. Within this context, phase change materials and systems dynamic interactions seem to be crucial substances for comprehension in the light of challenging issues, which are still unsolved. Synergies with established tools and standards and efficient symbiosis taking into account the dynamics and hidden potential provide a deeper insight, due to materials’ impact on the whole economic and social life of human activities, the built environment, the production and consumption systems, and the supply chain procedures, to name some.

The Special Issue seeks to identify contributions referring to design and modeling of latent storage systems, the quality of phase change materials and system dynamics interactions, business and management model deployment, phase change materials and energy stock and flows in ecological processes, the functionality and optimal operation research modeling, nature-inspired design and biomimicry, decision-making processes, and indirect metamaterials analysis effects. Best practices and case studies are also welcome.

The melting heat transfer of nano-enhanced phase change materials was addressed in a thermal energy storage unit. A heated U-shape tube was placed in a cylindrical shell. The cross-section of the tube is a petal-shape, which can have different amplitudes and wave numbers. The shell is filled with capric acid with a fusion temperature of 32 °C. The copper (Cu)/graphene oxide (GO) type nanoparticles were added to capric acid to improve its heat transfer properties. The enthalpy-porosity approach was used to model the phase change heat transfer in the presence of natural convection heat transfer effects. A novel mesh adaptation method was used to track the phase change melting front and produce high-quality mesh at the phase change region. The impacts of the volume fraction of nanoparticles, the amplitude and number of petals, the distance between tubes, and the angle of tube placements were investigated on the thermal energy rate and melting-time in the thermal energy storage unit. An average charging power can be raised by up to 45% by using petal shape tubes compared to a plain tube. The nanoadditives could improve the heat transfer by 7% for Cu and 11% for GO nanoparticles compared to the pure phase change material. Full article
