Gas-liquid phase change heat and mass transfer enhancement aim to significantly improve the efficiency and stability of condensation, evaporation, and boiling processes by designing micro/nano-structured surfaces (e.g., bio-inspired superhydrophobic/hydrophilic coatings, porous media), optimizing two-phase flow (e.g., bubble/droplet dynamics regulation), and coupling multi-physics interactions (thermal-fluid-mass synergy). These technologies address critical challenges such as localized overheating, energy loss, and device size limitations in high heat flux scenarios. Key applications span energy systems (heat pumps, nuclear reactor cooling), electronics thermal management (chip two-phase cooling, data center liquid cooling), chemical process intensification (distillation, membrane desalination), and aerospace thermal control (microgravity phase change cooling). Future research focuses on precise control of phase-change interface dynamics, durability optimization of materials/structures under complex operating conditions, and cross-scale design driven by smart responsive surfaces and machine learning, fostering advancements in system efficiency, compactness, and sustainability.
