超临界流体由于在化工和能源系统中的广泛应用而成为近年来的研究热点。由于超临界/近临界流体在近临界区具有敏感的热输运特性，无论是在微重力条件下还是在陆地条件下，其热输运行为都是一个非常有趣和具有挑战性的课题。本文简要介绍了利用干涉仪进行流体对流换热相关临界现象的可视化实验。由于临界流体性质变化敏感，超临界流体行为的控制和测量非常困难。在这篇综述中，非侵入式可视化系统的干涉法进行了介绍和分析，在近临界区的流体实验研究。对于近临界和超临界实验，温度/密度控制和参数分析至关重要。本文还对临界流体的边界条件、对流行为和能量传递模式的分析进行了评述，并对今后的发展提出了一些看法。希望能对相关研究有所帮助。
Supercritical fluids have become a hot topic in recent years, due to their wide applications in chemical and energy systems. With its sensitive thermal-transport properties in the near-critical region, supercritical/near-critical fluids behaviors, under both microgravity and terrestrial conditions, have become very interesting and challenging topic. This brief review is focused on the visualization experiments of fluid convection and heat transfer related critical phenomena by interferometer. Due to the sensitive property changes of critical fluids, it is very difficult to control and measure the supercritical fluid behaviors. In this review, non-intrusive visualization systems by interferometry are introduced and analyzed for experimental studies of fluids in the near-critical region. For near-critical and supercritical experiments, the temperature/density control and parameter analysis are of critical importance. The analysis of boundary conditions, convection behaviors and energy transfer modes of critical fluids, mainly under weightlessness, are also reviewed with recent opinions toward future development. It is hoped that this review could be helpful for related studies.
