Backscatter in stratified turbulence
(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
(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, ... -
Short-wave vortex instability in stratified flow
(Elsevier, 2016-01)In this paper we investigate a new instability of the Lamb–Chaplygin dipole in a stratified fluid. Through numerical linear stability analysis, a secondary peak in the growth rate emerges at vertical scales about an order ...
