Abstract: Results of simulations of the flow structure in a vertical monodisperse gas-liquid flow in a tube on the basis of the Euler approach with allowance for the effect of bubbles on the averaged characteristics and turbulence of the carrier flow are reported. The carrier phase turbulence is calculated by using the transport model for the Reynolds stress tensor components. A comparison of the simulation results with available experimental data shows that the proposed apprach provides an adequate description of turbulent bubble flows in wide ranges of the local gas content and gas inclusion sizes.

Keywords: gas-liquid flow, simulation, flow structure, turbulence.
