Abstract This paper provides a comprehensive review of published articles addressing passive enhancement of pool boiling using surface modification techniques. They include macroscale, microscale, and nanoscale surfaces, as well as multiscale (hybrid-scale), and hybrid-wettability techniques. Different enhancement methods are assessed in terms of underlying fluid routing mechanisms and ability to achieve three distinct heat transfer goals: eliminating incipient boiling hysteresis, increasing nucleate boiling heat transfer coefficient, and ameliorating critical heat flux (CHF), especially for inert dielectric coolants that are both highly wetting and possess relatively poor thermophysical properties. While different enhancement scales are shown to provide different degrees of success in achieving the three goals, it is shown that both microscale and nanoscale surface features are susceptible to blockage, resulting in deterioration of the enhancement over time. This review also points to scarcity of sufficiently sized databases for a given enhancement scheme in terms of fluid type, surface material, size, and orientation, enhancement shape, pattern, and scale, and operating pressure. This renders available findings less-than-adequate tools for design of practical cooling systems.

表面改性增强池沸腾的研究进展

摘要 本文对使用表面改性技术被动增强池沸腾的已发表文章进行了全面审查。它们包括宏观尺度、微观尺度和纳米尺度表面，以及多尺度（混合尺度）和混合润湿性技术。根据潜在的流体路由机制和实现三个不同传热目标的能力评估不同的增强方法：消除初始沸腾滞后、增加核沸腾传热系数和改善临界热通量 (CHF)，特别是对于惰性介电冷却剂两者都具有高度润湿性和相对较差的热物理特性。虽然显示出不同的增强尺度在实现三个目标方面提供不同程度的成功，结果表明，微米级和纳米级表面特征都容易受到阻塞，导致增强效果随着时间的推移而恶化。该评论还指出，在流体类型、表面材料、尺寸和方向、增强形状、模式和规模以及操作压力方面，缺乏足够大小的数据库用于给定的增强方案。这使得可用的发现不足以用于设计实际冷却系统的工具。
