Abstrakt: We focused on the study of the local hydrodynamics of liquid in gas-liquid flow in thingap microchannels (width 10 mm, depth 2 mm - 0.1 mm). Two-phase flow was obtained by injecting bubbles into the channel to mimic the gas generation during electrochemical reactions. The liquid flow velocity vectors were obtained by the PIV technique. Single phase measurements were used to verify our method by comparison with the theoretical velocity profiles. Local velocity fields around single bubble were evaluated.
