This paper reports measurements on gas phase turbulence made in vertical annular flow. Measurements were first carried out with single-phase gas flow to check the measurement technique/test section combination was working correctly. Laser anemometry techniques have been employed to measure gas velocities in annular two-phase flow. Mean velocities and Reynold's stresses in the gas appear to be similar to those in corresponding rough pipes. However, turbulence intensities are higher than the values corresponding to flow over a wall with a roughness equivalent to the film interface.
