Summary

Microscale heat transfer plays an increasingly important role in addressing the global demand for efficient, sustainable, and clean energy technologies. As energy systems continue to evolve toward higher compactness, multifunctionality, and integration with renewable sources, understanding transport phenomena at small scales becomes crucial. Investigating thermal transport at the micro- and nanoscales enables advancements in energy conversion, storage, and utilization, while also contributing to the development of innovative materials and system architectures.


This special issue aims to provide a platform for the dissemination of recent progress in microscale heat transfer with a particular focus on renewable energy applications. We invite contributions that explore fundamental mechanisms, emerging physical insights, advanced modeling techniques, and experimental investigations relevant to micro- and nanoscale transport. Studies that bridge traditional thermal science with energy engineering, materials science, or environmental applications are especially welcome.


Topics of interest include but are not limited to:
• Microscale and nanoscale heat and mass transfer
• Renewable energy system optimization involving microscale transport
• Phase-change processes and compact thermal energy storage
• Microfluidic structures and flow control for energy applications
• Surface engineering and material design for enhanced thermal transport
• Multiscale simulation and measurement techniques for transport phenomena

    Effects of Wear-Induced Surface Roughness and Pore Taper on the Performance of Porous ZnS/Ag High-Temperature Solar Absorbers

    Haiyan Yu, Mingdong Li, Ning Guo, Fengying Ren, Yongheng Lu, Mu Du

    Abstract High-temperature radiative cooling is essential for solar absorbers, as it mitigates efficiency degradation resulting from thermal accumulation. While porous structures have proven effective in enhancing absorber performance, practical manufacturing processes and prolonged operational wear inevitably introduce surface roughness and structural deviations, which profoundly impact radiative properties. This study constructs a ZnS/Ag solar absorber model with surface roughness and employs the finite-difference time-domain method to investigate how characteristic length, surface roughness, porosity, pore shape factor, and taper influence its radiative properties in the 3 μm–5 μm band at 750 K. Results show optimal absorption at a More >
