Laboratory Observations of Oscillatory Flow Over Sand Ripples
These datasets comprise of laboratory observations of oscillatory flows over mobile sand ripples. The data were collected in the Small-Oscillatory Flow Tunnel (S-OFT) in the Sediment Dynamics Laboratory at the U.S. Naval Research Laboratory, Stennis Space Center, Mississippi (MS), while Donya Frank-Gilchrist was a National Research Council post-doctoral fellow there. The flow tunnel has a 2-m long acrylic test section which was filled with coarse quartz sand. A piston and flywheel were used to drive the oscillatory flows, from which equilibrium sand ripples developed. The experimental setup comprised of three Photron cameras and a double-pulsed Litron Nd:YAG laser, synced and sampled at 100 hertz in double-framed mode. The fluid velocities were obtained through Particle Image Velocimetry processed with LaVision DaVis v.11 software.
