摘要：
A device for studying hydrodynamics and heat transfer in helium flow (helium being in two-phase liquid, and supercritical states) is described. Preliminary data about pressure drop and heat transfer in two-phase helium flow are presented. The tube used was about 0.45 mm i d and about 1 m long. The mass flow in the tests ranged from 1·5 × 10-2 gls, heat flux from 0·02 to 0·5 W/cm2 and quality x (mass vapour fraction) ranged from 0 to 100%. The dependence of Δp/[xΔpv + (1 - x)Δp1] on x is found to be a convenient (in the opinion of the authors) form of presentation of experimental two-phase pressure drop data. © 1969.
