Turbulent Mixing in 2-D and 3-D Density Currents over a Slope

Mixing within density currents plays a fundamental role in predicting and understanding the dynamics of dense current propagation, which are often encountered in the natural environment and numerous fields of science and engineering, including geosciences, geophysics, hydraulics, limnology, oceanography, snow mechanics, and weather prediction [1]. Turbulent mixing of dense and ambient fluids is also a key process for both coastal and deep ocean circulation. The mechanism and dynamics of entrainment or mixing in overflows that are generated at high altitudes, and descend through the continental slope to ocean basins, have been extensively investigated, as a result of their global importance in thermo haline circulation [2-9].
