Summary
Phase-change heat transfer and interfacial transport phenomena play critical roles in advanced thermal management, energy conversion, and high-heat-flux applications. With the rapid development of high-power electronics, renewable energy systems, hydrogen technologies, and low-carbon energy conversion processes, achieving efficient heat and mass transfer at solid–liquid, liquid–vapor, and multiphase interfaces has become increasingly important. However, the complex interactions among surface structures, fluid dynamics, phase-transition processes, and molecular-scale mechanisms remain challenging to fully understand and regulate.
This Special Issue aims to provide a platform for recent advances in fundamental mechanisms, experimental investigations, and numerical simulations of advanced heat and mass transfer processes in phase-change energy systems. Contributions focusing on innovative enhancement strategies, multiscale modeling approaches, and emerging applications are particularly encouraged.
The topics of interest include, but are not limited to:
· Boiling and condensation heat transfer enhancement;
· Interfacial transport phenomena in multiphase systems;
· Micro/nanoscale heat transfer and molecular dynamics simulations;
· Porous, composite, and nanostructured surfaces for thermal management;
· Spray cooling and droplet impact heat transfer;
· Bubble dynamics and mass transfer in energy conversion processes;
· Heat and mass transfer mechanisms in low-carbon and sustainable energy systems.
