| Abstract: | 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. |
