Abstract

Bubbly liquid flow through fixed beds and its transition to dispersed-bubble flow is analyzed. The system is described as a compressible fluid filtrating through porous media. The system peculiarities-the isothermal variation of perfect gas in the spherical bubbles, weak compressibility of the liquid, etc.-are accounted for in the state equation for bubbly liquid. Dimensionless criteria were found determining the bubbly-liquid flow in packings at the macro (bed) scale as well as criterion for its stability at the micro (pore) scale. The modeling results are compared with the experimental data.
