Two-phase bubble flow
TL;DR: In this article, a theory is presented which shows that the velocity of the bubbles consists of a component equal to the superficial liquid velocity, a component equivalent to the gas velocity and a component due to buoyancy.

Holdup and pressure drop with gas-liquid flow in a vertical pipe
G. A. Hughmark,B. S. Pressburg +1 more
TL;DR: In this paper, a statistical correlation for holdup was developed to include fluid physical properties, total mass velocity, and the air-liquid ratio entering the pipe, which showed an average percentage error of less than 15% between the observed and the calculated total pressure drop.

Properties of Cocurrent Gas-Liquid Flow
TL;DR: The problem of two-phase flow classification is complicated by the inevitable differences because of individual interpretations of visual observations and also by differences in terminology as mentioned in this paper, and a number of definite flow patterns are investigated.

Heat and mass transfer in vertical tubular bubble absorbers for ammonia-water absorption refrigeration systems
TL;DR: In this article, a model is developed for calculation of simultaneous heat and mass transfer processes in vertical bubble absorbers as used for ammonia-water absorption refrigeration systems, and the mass transfer coefficients resulting from these experiments are correlated by a modified Sherwood relation.

Analysis of a bubble absorber working with R22 and five organic absorbents
TL;DR: In this paper, a model of the absorption process in a vertical tubular bubble absorber working with R22-DMF, R 22-DMA, R22 -DMETEG and R 22 -NMP is developed using finite element method employing Galerkin's technique.
