Abstract

The paper is devoted to numerical modeling of flow of gas-liquid flux in horizontal and inclined tubes by one-dimensional model. By the help of developed numerical algorithm the parametric study of transition from stratified flow of water-air flux to the slug flow is carried out. In the case of slug regime the influence of tube inclination on the length and frequency of liquid slugs is studied.
