The transport of a dry gas through corrugated pipes can lead to flow-induced pulsations, which can result in tonal noise production and fatigue failure of the pipe or coupling. The unwanted effect can be prevented by increasing the liquid content. The effect of liquid on the one flow-induced pulsations is yet unknown, but one of the proposed mechanisms is mixing-layer disruption by droplets or damping by liquid on the wall. In this master thesis the effect of liquid droplets on a cavity mixing-layer is investigated. The behaviour of droplets in a cavity mixing-layer has been determined experimentally using shadowgraphy. From the experiments it was concluded that the small droplets are influenced by the cavity mixing-layer and large droplets impact on the cavity wall. Lowering the cavity Reynolds number resulted in a larger spreading of the droplet distribution and more droplet impacts at the downstream cavity wall.
