APPLICATION OF THE ELECTROCHEMICAL METHOD FOR MEASURING THE FLUID VELOCITY IN A TWO-PHASE BUBBLE FLOWO. N. Kashinskii, E. V. Kaipova, and A. S. Kurdyumov UDC 532.529.5 A technique for measuring the fluid velocity in a two-phase flow using a combination of the electrochemical method and the conduction method is described. The point of this technique is numerical analysis of complete realizations of signals from the electrodiffusion velocity transducer. The dependence of the results of measurements of local hydrodynamic characteristics of the bubble flow on the level of gas-phase cutting out has been investigated. The measurement data for the local gas content, the fluid velocity, and the velocity pulsations during bubble mixture motion in a tilted channel are presented. S. S.
