Summary
The incentive for reducing greenhouse gas emissions encourages blooming studies for energy saving, solar energy harvesting and green energy usage. Meanwhile, the minimization of electronic devices with performance improvements for coping with the implementation of AI and communication technologies urges advancements in cooling technologies. Passive heat transfer enhancements for single-phase and multi-phase flows play an essential role in the prospective developments of these engineering fields, such as efficiency increases for heat exchangers, heat engines, and power plants, improvements of energy conversion performance for green energy harvesting, and elevations of power densities for electronic components/systems and electric machinery. This Special Issue is dedicated to the novel results in theoretical, experimental, and numerical studies of passive heat transfer enhancements for single-phase and multi-phase flows. The current advancements in the research methods for exploring the thermal and flow physics relevant to passive heat transfer enhancements are also of interest.
Topics of interest include, but are not limited to:
• Passive heat transfer enhancement for single- and two-phase flows;
• Cooling enhancements of internal combustion engines;
• Performance improvements of the heat pipe, thermosyphon and vapor chamber;
• Heat/mass transfer enhancement in proton-exchange membrane fuel cell;
• Heat transfer enhancements by insert technology;
• Solar and geothermal energy harvesting;
• Heat exchanger;
• Electronic cooling;
• Novel methods in experiments, modeling and simulation of heat transfer enhancement.
