The analysis of gas-liquid intermittent flow in horizontal pipes is of great relevance importance due its applications in many industrial problems, such as in the petroleum industry, boiler and heat exchanger tubes and cooling systems of nuclear power plants. A considerable number of experimental and analytical studies have been carried out on the pursuit of a deeper knowledge of this complex phenomenon. The present work describes an experimental study of a horizontal, gas-liquid pipe flow in the intermittent regime. Experimental techniques such as high frequency stereoscopic particle image velocimetry (SPIV ) and laser induced fluorescence (LIF), were applied in order to obtain all three components of the velocity vector at different pipe sections, referred to the gas bubble nose tip. A 40mm inner diameter, 17.7m long acrylic pipe was used as test section (L/D approximately 450). The working fluids, water and air formed the intermittent flow pattern, with superficial velocities of jL equal 0.3, 0.4 and 0.5 m/s and jG equal 0.5 m/s. A set of three photogate sensors, equally-spaced along the pipe, were used to measure the bubble translational velocities, and to trigger the SPIV system, allowing for the determination of ensemble-averaged, threecomponent velocity fields of the turbulent liquid flow in cross-stream planes around the gas bubble. The original data obtained revealed the influence of the faster-moving gas bubbles on the dynamics of the liquid velocity field, providing valuable information that contribute to a better understanding of the physics governing the flow, also serving for the validation of numerical simulations.
