Turbulence Spectra in a Well-Mixed Estuary
… using standard digital methods to obtain spectral density, spectral energy, and cross-spectra of velocity. In order to study the generation and transfer of the turbulent moment and energy, and the intermittent nature of the so-called "Bursting or "ejections and sweeps," the distribution of …

Three-Dimensional Fluid Simulations of Mid-Latitude Ionospheric Processes with Hybrid Chebyshev/Fourier Pseudo-Spectral Methods
… roles in driving mid-latitude ionospheric turbulence and irregularities.par Initial investigations involved a two-dimensional (2D) numerical model to study density irregularities in the Subauroral Polarization Streams (SAPS). This model analyzed the turbulence spectra of the GDI. Previous …

Observations of turbulent fluxes and turbulence dynamics in the ocean surface boundary layer
This study presents observations of turbulence dynamics made during the low winds portion of the Coupled Boundary Layers and Air-Sea Transfer experiment (CBLAST-Low). Observations were made of turbulent fluxes, turbulent kinetic energy, and the length scales of flux-carrying and energy-containing …

Very large eddy simulations of spatially evolving supersonic turbulent shear layers
… fundamental physical mechanisms which control turbulence and entrainment at different levels of compressibility for supersonic shear flows. Very Large Eddy Simulations (VLES) were performed based on the two-dimensional unsteady Euler equations without any empirical coefficients for turbulence …

Turbulence structure of a model seagrass meadow
… The principal goal was to characterize the turbulence structure of a depth-limited canopy, a gap that presently exists in the knowledge concerning the interaction of a unidirectional flow with an assemblage of plants. The experiments were carried out in an open channel flume with a model …

Large-Eddy Simulations of Hydrocyclones
This dissertation investigates the flow physics, turbulence structure, and particle classification process in hydrocyclones using large-eddy simulations of turbulent multiphase flow. Two types of hydrocyclones are considered. The first is a classifying hydrocyclone, and the second is a mineral …
