Application of the Eulerian approach to simulating the structure of an upward monodisperse bubbly flow in a tube

Abstract

The structure of a vertical monodisperse gas–liquid flow in a tube is simulated by the Eulerian approach with allowance for the influence of bubbles on the averaged characteristics and turbulence of the carrier phase. The turbulence of the carrier phase is calculated by the model of transport of the Reynolds stress tensor components. A comparison of the simulation results with available experimental data shows that the developed approach provides an adequate description of turbulent bubbly flows in wide ranges of gas flow rate ratios and gas bubble sizes.
