Visualization in Cryogenic Environment: Application to Two Phase Studies

Abstract

Visualization techniques compatible with low temperature environment are essential in the extension of room temperature techniques to the study of cryogenic flows. Focusing on two-phase fluids, this paper describes several optical tools developed in severe environments (high magnetic field, superfluid flows,...) to access two-phase patterns (meniscus shape, bubbles and droplets, stratified two-phase flows...).
