  • Turbulence and biophysical fluxes in the near surface ocean

    Creator:
    Hoecker-Martínez, Martín
    Abstract:
    Vertical transports of plankton, momentum, heat, and turbulence are modeled. A novel integration of high resolution turbulence and biophysical modeling is used to show the influence of a Kelvin-Helmholtz instability on the vertical migration of simple gyrotactic organisms. A viscous limit on mixing driven by shear turbulence is proposed. Large...

  • DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

    Creator:
    Ghodke, Chaitanya Deepak
    Abstract:
    Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...
