Sutanu Sarkar Professor Mechanical and Aerospace Engineering DepartmentUniversity of California at San DiegoLa Jolla, CAABSTRACT:Background fluid stratification, often prevalent in the environment, inhibits vertical turbulent motion, allows wave-like motion, and promotes the formation of coherent structures. Quantification of the dynamical pathways that lead to mixing in spite of stable stratification is of critical interest to environmental modeling including local and regional impact of climate change. Our work utilizes high-resolution numerical resolution to understand links between turbulence, internal waves and coherent vortices. We will discuss the following examples from our recent work on turbulent flows in the ocean: a jet with non-uniform stratification as a model for vertical mixing in Equatorial Under Currents, a boundary layer on a sloping bottom as a model for mixing on a continental slope and finally the wake of a self-propelled submersible.
