The experimental research on the ascending gas-liquid slug flow in a vertical pipe has been conducted. Measurements have been performed by the electrochemical method. A technique of provisional realization ensemble averaging has been practiced and used to measure distributions of liquid velocities in a liquid plug depending on the distance from the start of the slug. It is shown that, in the initial area of the liquid plug, a considerable deformation of liquid velocity profiles takes place, as compared to a one-phase flow, which is the result of the influence of a toroidal vortex flowing from under the previous gas slug. The behavior of friction at the wall corresponds completely to the liquid velocity behavior in the near-wall area of the flow.
