- Summary
-
The two-phase flow parameters were found to change significantly with superficial liquid velocity and quality in this low-circulation range. Slip ratios were found to be directly proportional to the surface tension of the liquid, and inversely proportional to the dynamic viscosity of the liquid. Dimensional analysis was used to correlate slip ratios and gas-to-liquid holdups as a function of four dimensionless groups which included the liquid circulation rate, the gas circulation rate, the surface tension of the liquid, the dynamic viscosity of the liquid, the density of the liquid, the density of the gas, the pipe diameter, and the acceleration due to gravity.
Two-phase flow parameters for upward cocurrent vertical flow were studied in air-water, nitrogen-Freon-113, and nitrogen-mercury mixtures. Tests were performed in natural-circulation loops at atmospheric pressure. The superficial liquid velocity ranged from 0 to 1 ft/sec; quality ranges were as follows: for air-water, 0.0125 to 0.100; for nitrogen-Freon-113, 0.002 to 0.006; for nitrogen-mercury, 0.00005 to 0.0024. The studies of air-water and nitrogen-Freon-113 mixtures were made in 2.75-in.-ID test section; the nitrogen-mercury study was made in a 2-in.-ID pipe.
