About this Research Topic
The condensation phenomenon occurs frequently both in nature and in engineering. In many industrial processes where the working gas (such as steam, air and etc.) takes part in the process of energy conversion or energy transport may exist a fog of micro- or nanoscale droplets, coarse liquid or liquid films. It may happen in steam turbines, air compressors, ejectors, purification systems, desalination industry, separators, and condensers. In many technical applications, the condensation phenomenon is triggered and enhanced in purpose, like in HVAC&R (Heating, Ventilation, Air Conditioning, and Refrigeration), solar distillation unit and supersonic separator. However, condensation is an undesirable problem for the aircraft industry due to a large amount of vapor in the atmospheric air while the droplets and film formed by vapor condensation in turbine and ejector can reduce the working efficiency and cause corrosion and erosion on solid surface. Therefore, it is necessary to comprehensively and accurately obtain and predict the micro- or nanoscale condensation heat transfer in two-phase flows that require higher energy efficiency or concentrated thermal loads for cooling.
This Research Topic aims to address the heat and mass transfer problem of condensing flows. Our attention will be paid to the steady and transient condensation processes, including experimental research, numerical modeling and the heat and mass transfer identification during the condensation process. To enhance the machines and device’s performance and durability as well as to improve the safety of the industrial processes, the studies must include controlling the condensation and the device structure optimization. In addition, another aim is finding the appropriate methods for reducing the corrosion caused by droplet generation and liquid film formation.
This Research Topic focuses on recent advancements in condensing flows. We welcome submissions of Original Research articles, Review articles, and other papers. Suggested topics are as follows, but are not limited to:
• Non-equilibrium / Equilibrium condensation physics

• Performance enhance of industrial devices working with phase change
• Corrosion and erosion caused by liquid droplet and film formation
• Condensation in heat exchangers
• Falling film evaporation and condensation
• Two phase surface interactions
• HVAC&R (Heating, Ventilation, Air Conditioning, and Refrigeration)
• Heat transfer enhancement techniques in condensing flows
• Novel measurement techniques in phase change processes
