An Anisotropic Subgrid-Scale Parameterization for Large-Eddy Simulations of Stratified Turbulence

Khani, Sina; Waite, Michael L (AMS, 2020-10-01)

Subgrid-scale (SGS) parameterizations in atmosphere and ocean models are often defined independently in the horizontal and vertical directions because the grid spacing is not the same in these directions (anisotropic ...
Backscatter in stratified turbulence

Khani, Sina; Waite, Michael L (Elsevier, 2016-11)

In this paper, kinetic and potential energy transfers around a spectral test fil ter scale in direct numerical simulations of decaying stratified turbulence are studied in both physical and spectral domains. It is shown ...
Large eddy simulations and subgrid scale motions in stratified turbulence

Khani, Sina (University of Waterloo, 2015-03-18)

Direct numerical and large eddy simulations (DNS $\&$ LES) of decaying and forced stratified turbulence are studied in this thesis. By defining a test filter scale $k_c$ in the horizontal and vertical directions separately, ...
