Data for the two‐dimensional velocity and size of entrained drops carried by the gas core during upward annular gas liquid flow are presented. The measurements of velocity and size were made simultaneously using a new experimental technique. Information on the variation of the drop velocity with flow rates, radial position in the core, and drop size are presented and analyzed. Droplet velocity is shown to increase with size, counter to intuitive expectation. This is explained in terms of highly modified drag‐Reynolds number relationships caused by the high turbulence level in the core.
