Efficient management and exploitation of thermal energy is key for many engineering applications. Greater understanding and control of thermal processes, such as thermal energy harvesting, storage and transfer will play an important role in achieving the UN SDGs. We announce a call for papers in the journal Communications Engineering, with a view to the publication of a collection of papers on the topic of thermal engineering with a particular focus on applications related to sustainability. The collection will explore:
Design and optimization
• Passive heat transfer enhancement and optimization e.g. evaporation and condensation
• Computational techniques
• Innovative materials e.g. thermal metamaterials, phase change materials
Technologies and applications
• Thermal energy management for temperature control of buildings, infrastructure etc, for example heat exchangers, heat pumps and other heat transfer equipment, radiative cooling
• Thermal energy harvesting and storage from low carbon sources including waste heat, solar
• Exploitation of low carbon thermal energy for example solar thermal power generation, solar desalination
Yu and colleagues report a modified and flexible Evans-Perkins heat pump cycle integrating heat recovery and storage and demonstrate its application in a prototype heat pump. The recovered heat can be used as an ancillary heat source for the heat pump’s operation and to defrost the heat pump evaporator as necessary.
A recent publication in Proceedings of the National Academy of Sciences describes a fluid-based building interface to reduce energy use for heating, cooling and lighting by selectively tuning light absorption and dispersion. Models showed that this system could reduce the annual energy consumption by up to 43% compared to existing technologies.
