RISLarge Eddy Simulations of a Stratified Shear Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of the large eddy simulation (LES) approach in predicting the evolution of a shear layer in the presence of stratification is evaluated. The LES uses a dynamic procedure to compute subgrid model coefficients ...
Interaction between upper-ocean submesoscale currents and convective turbulence

Near-N Oscillations and Deep-Cycle Turbulence in an Upper-Equatorial Undercurrent Model
Publisher: American Meteorological Society
Abstract: irect numerical simulation (DNS) is used to investigate the role of shear instabilities in turbulent mixing in a model of the upper Equatorial Undercurrent (EUC). The background flow consists of a westward-moving surface ...
Large-Eddy Simulation of Deep-Cycle Turbulence in an Equatorial Undercurrent Model
Publisher: American Meteorological Society
Abstract: ynamical processes leading to deep-cycle turbulence in the Equatorial Undercurrent (EUC) are investigated using a high-resolution large-eddy simulation (LES) model. Components of the model include a background flow similar ...
Deep-Cycle Turbulence in the Upper Pacific Equatorial Ocean: Characterization by LES and Heat Flux Parameterization
Publisher: American Meteorological Society
Seasonality of Deep Cycle Turbulence in the Eastern Equatorial Pacific
Publisher: American Meteorological Society
Abstract: AbstractThe seasonal cycles of the various oceanic and atmospheric factors influencing the deep cycle of turbulence in the eastern Pacific cold tongue are explored. Moored observations at 140°W have shown seasonal variability ...
Second Moment Closure Modeling and Direct Numerical Simulation of Stratified Shear Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buoyant shear layers encountered in many engineering and environmental applications have been studied by researchers for decades. Often, these flows have high Reynolds and Richardson numbers, which leads to significant/intractable ...
A Finite-Time Ensemble Method for Mixed Layer Model Comparison
