000013879 520__ $$2eng$$aThe combination of PIV, conductance probing and hot wire anemometry allows us to obtain deeper insight into the physical mechanisms that govern stratified gas-liquid pipe flows. In this paper, we turn our attention towards one of such mechanisms; wave-induced fluctuations in the air velocity field and we raise two questions that will hopefully be answered in future analysis of the present data set. Gas-phase PIV was achieved by using water droplets to seed the gas-phase and provides us with instantaneous and phase-averaged velocity profiles. Conductance probes measured interface elevation at two positions in the axial direction, while a hot-wire probe measured air fluctuations at a set of points between the interface and the pipe wall. This combination of techniques demonstrates clearly how a deformed interface obliges the gas flow to fluctuate at the same frequency as the dominating interfacial wave components.
