Distribución de Fases en Flujo Bubbly Laminar Completamente Desarrollado

Abstract

The purpose of this paper is to analyze the phase distribution of an air-water, adiabatic, vertical, laminar, fully developed, bubbly flow in a cylindrical pipe. A two-fluid model is used, including equations for the conservation of mass and momentum, and the so-called closure laws. It is shown that the entire system can be collapsed into one single non-dimensional equation. The analysis of its solutions improves the understanding of the flow. It is shown that the gas fraction in the central region of the duct must adjust so that its weight equilibrates the imposed pressure gradient. The gas leaving the central region concentrates near the walls.
