pressure, to reach temperatures higher than 4.2 K. As was expected from Fig. la, the original data for the range from 2.25 to 5 K was found to be correct. However, data below the X-point (2.17 K) differed drastically in the two calibrations. The supplier could not explain this discrepancy, and the s

β¦ Synopsis
This paper describes a study performed to obtain the critical heat flux data on liquM helium I in a vertical tube under forced convection. The pressure of the fluid ranges from 1. 1 to 2.0 atm , and the quality up to 1. The results show that the critical heat flux decreases with increasing pressure and quafity.

Information about the quality and flow patterns of helium two-phase flow has been obtained by using optical fibres and photo-sensitive devices. Light emitted from a LED is scattered by bubbles and turbulence in liquid helium. As bubbles and turbulence in liquid are related to the quality, x, the mea
