Regimes of stratified turbulence at low Prandtl number
Kasturi Shah, Gregory P. Chini, Colm-cille P. Caulfield +1
Quantifying transport by strongly stratified turbulence in low Prandtl number () fluids is critically important for the development of better models for the structure and evolu…
Spatio-temporal characterization of non-linear forcing in turbulence
Yuting Huang, Simon S. Toedtli, Gregory P. Chini +1
The quadratic convection term in the incompressible Navier-Stokes equations is considered as a non-linear forcing to the linear operator, and it is studied in the Fourier domain th…
Exploiting self-organized criticality in strongly stratified turbulence
Gregory P. Chini, Guillaume Michel, Keith Julien +2
A multiscale reduced description of turbulent free shear flows in the presence of strong stabilizing density stratification is derived via asymptotic analysis of the Boussinesq equ…
Steady Rayleigh--Bénard convection between stress-free boundaries
Baole Wen, David Goluskin, Matthew LeDuc +2
Steady two-dimensional Rayleigh--Bénard convection between stress-free isothermal boundaries is studied via numerical computations. We explore properties of steady convective rolls…
A self-sustaining process theory for uniform momentum zones and internal shear layers in high Reynolds number shear flows
Brandon Montemuro, Christopher M. White, Joseph C. Klewicki +1
Many exact coherent states (ECS) arising in wall-bounded shear flows have an asymptotic structure at extreme Reynolds number Re in which the effective Reynolds number governing the…
Strong wave-mean-flow coupling in baroclinic acoustic streaming
Guillaume Michel, Gregory P. Chini
The interaction of an acoustic wave with a stratified fluid can drive strong streaming flows owing to the baroclinic production of fluctuating vorticity, as recently demonstrated b…
Reduced modeling of porous media convection in a minimal flow unit at large Rayleigh number
Baole Wen, Gregory P. Chini
Direct numerical simulations (DNS) indicate that at large values of the Rayleigh number () convection in porous media self-organizes into narrowly-spaced columnar flows, with m…
Reduced description of exact coherent states in parallel shear flows
Cedric Beaume, Gregory P. Chini, Keith Julien +1
Exact coherent states of a linearly stable, plane parallel shear flow confined between stationary stress-free walls and driven by a sinusoidal body force (a flow first introduced b…
Exact coherent structures in a reduced model of parallel shear flow
Cedric Beaume, Edgar Knobloch, Greg P. Chini +1
A reduced description of shear flows consistent with the Reynolds number scaling of lower-branch exact coherent states in plane Couette flow [J. Wang et al., Phys. Rev. Lett. 98, 2…
