Abstract

High-speed still and moving photographs, using diffused back lighting, associated with earlier studies [1,2] of heat transport from a horizontal wire to helium II were of limited value because of the poor definition of the boundaries between the liquid and gaseous phases. It was felt that the use of improved optical techniques would overcome this deficiency. This paper describes the use of focused shadowgraph and schlieren techniques for the visualization of heat transfer in helium II.
