Large-Eddy Simulation of Flow over Two-Dimensional Obstacles: High Drag States and Mixing

Creator:

Skyllingstad, Eric D. and Wijesekera, Hemantha W.

Abstract:

A three-dimensional large-eddy simulation (LES) model was used to examine how stratified flow interacts with bottom obstacles in the coastal ocean. Bottom terrain representing a 2D ridge was modeled using a finite-volume approach with ridge height (4.5 m) and width (~30 m) and water depth (~45 m) appropriate for coastal...

Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer

Creator:

Wijesekera, Hemantha W., Paulson, Clayton A., and Huyer, Adriana, 1945-

Abstract:

Horizontal wave number spectra of temperature in the unstably stratified oceanic surface layer were determined from measurements on a bow boom at a depth of 2 m. Spectra were estimated in the wavelength band from 2 m to 2 km, normalized in accordance with Monin-Obukhov similarity theory, and averaged in...
