摘要
低温流体在航天、医疗设备、大型超导实验装置以及工业过程等领域的应用正变得越来越多,而可视化是对低温流体的紊流和两相流体动力学等复杂流动现象进行研究的重要手段。对低温流体流动可视化研究使用的一些最新方法和技术进行了介绍,着重对不同低温流体流动可视化技术的原理与应用场合、实验系统的光学部件与设备要求、可视化观察的典型图像结果作了总结。
Cryogenic fluids have been widely used in many fields such as aerospace, medical application, superconducting magnet cooling, and industrial process. Flow visualization is a powerful technique to study complex phenomena such as two- phase flow dynamics, etc. This article introduces some recent techniques applied to flow visualization of cryogenic fluids at low temperatures. The emphasis is placed on the principles, applications and requirements for optical elements and equip- ments, and typical results by different flow visualization of cryogenic fluids techniques are presented.
