Air entrainment and bubble statistics in breaking waves

Three-dimensional Large Eddy Simulation of air entrainment under plunging breaking waves

The scope of this work is to present and discuss the results obtained from simulating three-dimensional plunging breaking waves by solving the Navier-Stokes equations, in air and water, coupled with a dynamic subgrid scale turbulence model (Large Preprint submitted to Coastal Engineering 23 January 2006 ha l-0 02 94 09 2, v er si on 1 8 Ju l 2 00 8 Author manuscript, published in "Coastal Engin...

Bubble entrainment by breaking waves and their influence on optical scattering in the upper ocean

Breaking waves at the ocean’s surface inject bubbles and turbulence into the water column. During periods of rough weather the scales of wave breaking will increase with increasing sea states and result in mixing of the surface waters and the turbulent transport of bubbles to depth. Depending on their concentrations and size distribution, the entrained bubbles can significantly change the optic...

Subharmonic resonant excitation of edge waves by breaking surface waves

We have added a new Figure 3, where we show two frequency spectra. The first spectrum (Figure 3 a) is in absence of the breaking waves, where the first peak indicates the edge wave frequency and the second peak indicates the surface elevation frequency. The second frequency spectrum (Figure 3 b) is plotted in presence of breaking wave and indicates the suppression of the peak for the edge wave ...

Local Air Entrainment and Detrainment

Air and water are usually well separated by gravity due to their extreme difference in specific weight. Whenever they are mixed, however, they give rise to a very complex two-phase flow situation. The hydraulic engineer is often faced with the problem of estimating the effects of entrained air upon the flow, because this may be essential for the safe operation of a hydra·ul ic structure. Depend...
