A new experimental approach to study two-dimensional flow phenomena is presented which uses a novel device capable of producing purely two-dimensional flows. In this new technique, a suspended liquid film (a soap film) is set in motion in a long frame using a planar water jet as a pulling mechanism. By producing film velocities up to 250 cm/s, this device can generate a variety of shear flows for quantitative studies via laser Doppler velocimetry. Several examples of shear flows are presented. It is shown that this device can be valuable tool in establishing a quantitative experimental basis for two-dimensional flows including wakes, jets, mixing layers and grid-generated turbulence.
