Heat transfer in branched channels filled with helium 2.

Author(s) : KOBAYASHI H., UCHIDA M., KAJIURA Y., KONAGAYA T., AKEDO Y.

Summary

The critical heat flux at which superfluidity is broken in branched channels was measured. A reduction in critical heat flux from the theoretical value becomes noticeable as the ratio of the channel width to the channel length increases. This geometry effect as a function of the aspect ratio "channel width/channel length" was used for the estimation of the stability margin of superconducting magnets cooled with atmospherically pressurized helium II.
