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

β¦ Synopsis
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 situation was further complicated by a change in the calibration current just above the X-point.

This paper reports the investigation of the structure of two-phase helium flows used for cryostatically controlling superconducting magnets in installations such as HERA, NET, UNK and KEK. Flow pattern maps for horizontal round channels and rectangular slot channels are plotted on the basis of exper
The performance of a venturi flow meter in vertical and horizontal two-phase helium flow is reported. In both flow configurations, tests were conducted by connecting two identical venturis of 2.29 mm throat and 4.57 mm inlet diameters in series with a twophase helium flow loop driven by a single-str
