The effect of bubbles on the structure of flow and the friction in downward turbulent gas-liquid flow

Results are given of a numerical study of local structure of downward gas-liquid flow in a vertical pipe. The numerical model is based on the use of two-liquid Eulerian approach. Investigation is performed of the impact made by the variation of the degree of dispersion of the gas phase, volumetric flow ratio of gas, channel diameter, and velocity of the liquid phase on the local structure and skin friction in two-phase flow.
