Péclet-number dependence of optimal mixing strategies identified using multiscale norms
Conor Heffernan, Colm-cille Caulfield
The optimization of the mixing of a passive scalar at finite Péclet number (where are characteristic velocity and length scales and is the scalar diffusivity) i…
Quantifying mixing and available potential energy in vertically periodic simulations of stratified flows
Christopher J. Howland, John R. Taylor, C. P. Caulfield
Turbulent mixing exerts a significant influence on many physical processes in the ocean. In a stably stratified Boussinesq fluid, this irreversible mixing describes the conversion…
The viscous Holmboe instability for smooth shear and density profiles
Jeremy P. Parker, Colm-cille P. Caulfield, Rich R. Kerswell
The Holmboe wave instability is one of the classic examples of a stratified shear instability, usually explained as the result of a resonance between a gravity wave and a vorticity…
The dynamics of stratified horizontal shear flows at low Péclet number
L. Cope, P. Garaud, C. P. Caulfield
We consider the dynamics of a vertically stratified, horizontally-forced Kolmogorov flow. Motivated by astrophysical systems where the Prandtl number is often asymptotically small,…
Asymptotic dynamics of high dynamic range stratified turbulence
G. D. Portwood, S. M. de Bruyn Kops, C. P. Caulfield
Direct numerical simulations of homogeneous sheared and stably stratified turbulence are considered to probe the asymptotic high-dynamic range regime suggested by Gargett et al. 19…
Self-organized criticality of turbulence in strongly stratified mixing layers
Hesam Salehipour, W. R. Peltier, C. P. Caulfield
Motivated by the importance of stratified shear flows in geophysical and environmental circumstances, we characterize their energetics, mixing and spectral behavior through a serie…
