Instantaneous velocity profiles in vertical and horizontal gas-liquid slug flows were recorded using a modified hydrogen bubble technique. The propagation velocity of the elongated bubble was found to be related to the maximum instantaneous liqud velocity ahead of it. The knowledge of the velocity field in the wake of the leading bubble is utilized to estimate the bubble translational velocity and the minimum stable slug length.
