“…Kuncoro et al [28] observed single large bubble covering the entire flow cross section flowed up while rapidly increasing its size due to evaporation from the surrounding superheated liquid. This observation was different from that by Aritomi et al [22] and Hands et al [29] who claimed that the upward-flowing single bubble enhanced the generation of more bubbles due to decrease of the static pressure. These were the two mechanisms related with geysering which were also reported by Griffith [30] based on his visual observations.…”

“…Then cryogenic two-phase flow is unavoidable. The propagation and storage of cryogenic liquids bring many problems, such as geysering, stratification and rollover (Hands 1988). Above phenomenon can cause high transient pressures and vapor flow rates, in some cases sometimes large enough to damage equipment.…”

An experimental study was carried out to understand the phenomena of the boiling flow of liquid nitrogen in inclined tubes with closed bottom by using the high speed motion analyzer. The tube in the experiment is 1.0 m length and 0.018 m and 0.014 m inner diameter respectively. The range of the inclination angles is 45-90 • from the horizontal. The statistical method is employed to analyze the experiment data. The experiment focused on the effect of the inclination angle on the distributions of the liquid slug length along the tube. The experimental results show that the Taylor bubble is easier to coalescence with inclination angle decreasing, but coalescence lessening at 45 • . The liquid slug length distributions extend to much larger values for the large tube when x/D is 40 and 50. The mean liquid slug lengths increased first, and then decreased with decreasing θ for two tubes, maximum at 60 • .

An experimental study was carried out to understand the phenomena of the boiling flow of liquid nitrogen in inclined tubes with closed bottom by using a high speed motion analyzer. The experimental tubes are 0.018 and 0.014 m inner diameter (ID) and 1.0 m in length. The range of the inclination angle is 45 • -90 • from the horizontal. The experimental observation on the liquid slug was carried out along the tubes. Statistical method was employed to analyze the experimental data. The experiment analyzed the influences of the inclination angle and the tube diameter on the liquid slug length and velocity. The results show the liquid slug propagation velocity increases with the decrease of inclination angle θ. For all cases, the maximum values of the mean liquid slug lengths were obtained at θ = 60 • . The mean liquid slug lengths were greater for large tube at higher tube position. These conclusions provide a basis for further study liquid slug of cryogenic two-phase undeveloped slug flow.
