EXPERIMENTAL RESEARCH ON SURFACE-GRAVITY WAVE ENERGY DISSIPATION

Explore an experiment by Ivan Savelyev at the Rosenstiel School of Marine and Atmospheric Science on air-sea interaction in a salt-water tank. The study includes three water wave impulses of different frequencies generated to create a focused breaking wave. The flow field during laboratory simulations is analyzed, with panels showcasing velocity fields in the air and water, mean velocity fields, and rms perturbation velocity fields during wave breaking. Techniques like Particle Image Velocimetry (PIV) and Laser Elevation Gauge (LEG) are employed, and water elevation series are sampled before the breaking event.

  1. EXPERIMENTAL RESEARCH ON SURFACE-GRAVITY WAVE ENERGY DISSIPATION Ivan Savelyev - Rosenstiel School of Marine and Atmospheric Science

  2. Air-Sea Interaction Salt-Water Tank

  3. Example of 3 water wave impulses of different frequencies, generated by paddle at the end of the tank in order to create focused breaking wave.

  4. Flow field during simulation of laboratory experiments. Top left panel shows velocity field in the air. Lower left panel is a 3-D view of the same moment. The mean velocity field is plotted in the water in the upper right panel, and the rms perturbation velocity field is plotted during the wave breaking event.

  5. Particle Image Velocimetry (PIV) – left, Laser elevation gauge (LEG) – right.

  6. Water elevation series sampled two meters before breaking event.
