numerical simulation of downslope flows in a confined stratified region
geophysical fluids such as atmosphere and ocean often have stable density stratification; hence internal gravity waves are generated and propagated through them which are important in momentum and energy transfer in these media. these waves are also believed to generate layered structures in such media. recently there have been numerous theoretical, experimental and numerical studies on the way...
متن کاملOn the Stability of Stratified Flows with a Horizontal Shear
Howard’s semi-circle theorem [4] states that the complex wavespeed for an unstable mode must fall within the range of values of the base flow, a conclusion that has proven to be of fundamental importance for a wide variety of flow phenomena. Howard’s original proof applies to a two-dimensional basic state, u(z), where z is the vertical distance and u is the horizontal velocity, with two dimensi...
متن کاملAnalytical and Numerical Studies on Stratified Fluid Flows
CLAUDIO VIOTTI: ANALYTICAL AND NUMERICAL STUDIES ON STRATIFIED FLUID FLOWS. (Under the direction of Roberto Camassa and Richard M. McLaughlin.) The mathematical modeling of stratified fluid flows is the overall subject of this work, which spans a range of more specific topics: internal gravity waves, shear instability, anomalous diffusion of passive scalars, vortex rings dynamics in stratified ...
متن کاملNonlinear wave-wave interactions in stratified flows: Direct numerical simulations
To investigate the formation mechanism of energy spectra of internal waves in the oceans, direct numerical simulations are performed. The simulations are based on the reduced dynamical equations of rotating stratified turbulence. In the reduced dynamical equations only wave modes are retained, and vortices and horizontally uniform vertical shears are excluded. Despite the simplifications, our s...
متن کامل2DV Nonlinear k-ε Turbulence Modeling of Stratified Flows
The commonly used linear k-ε turbulence model is shown to be incapable of accurate prediction of turbulent flows, where non-isotropy is dominant. Two examples of non-isotropic flows, which have a wide range of applications in marine waters, are saline water flow and the stratified flows due to temperature gradients. These relate to stratification and consequently, variation of density through...
