Abstract
An experimental study of the laminar, transient, and turbulent conditions of the flow of monodispersed gas-liquid mixtures with one-and two-millimeter bubbles has been made. Tube-parameter-averaged data on the development of friction stress on the wall and its pulsations have been obtained. The asymmetry parameter characterizing the nonuniformity of the friction stress distribution along the tube perimeter has been introduced. Flow conditions with a strong asymmetry have been revealed. The true gas content has been calculated by the Zuber-Hench formula [1]. For flow conditions with wall peaks of the gas content, the calculation data are in good agreement with the experimental data.
