[MM.005] Chemical pulses and superdiffusive transport in an oscillating-drifting vortex chain

Tom Solomon, Matt Paoletti (Department of Physics, Bucknell University, Lewisburg, PA 17837 USA)

We discuss experimental and numerical studies of transport and pulse propagation in an alternating vortex chain that can both oscillate and drift. Previous studies have shown that transport in the oscillating vortex is chaotic, with a variance that grows linearly with time; i.e., the transport is diffusive in nature. The addition of drifting to the vortex chain allows for superdiffusive transport with a variance that grows faster than linearly with time. We present particle-tracking data for transport in this system, along with experimental studies of the propagation of chemical pulses for the oscillating/drifting vortex chain.
