Small scale quasi-geostrophic convective turbulence at large Rayleigh number
Tobias G. Oliver, Adrienne S. Jacobi, Keith Julien +1
A numerical investigation of an asymptotically reduced model for quasi-geostrophic Rayleigh-Bénard convection is conducted in which the depth-averaged flows are numerically suppres…
Staircase solutions and stability in vertically confined salt-finger convection
Chang Liu, Keith Julien, Edgar Knobloch
Bifurcation analysis of confined salt-finger convection using single-mode equations obtained from a severely truncated Fourier expansion in the horizontal is performed. Strongly no…
Spontaneous suppression of inverse energy cascade in instability-driven 2D turbulence
Adrian van Kan, Benjamin Favier, Keith Julien +1
Instabilities of fluid flows often generate turbulence. Using extensive direct numerical simulations, we study two-dimensional turbulence driven by a wavenumber-localised instabili…
Experimental observation of the geostrophic turbulence regime of rapidly rotating convection
Vincent Bouillaut, Benjamin Miquel, Keith Julien +2
The competition between turbulent convection and global rotation in planetary and stellar interiors governs the transport of heat and tracers, as well as magnetic-field generation.…
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…
Connections between Non-Rotating, Slowly Rotating, and Rapidly Rotating Turbulent Convection Transport Scalings
Jonathan M. Aurnou, Susanne Horn, Keith Julien
Buoyancy-driven convection is likely the dominant driver of turbulent motions in the universe, and thus, is widely studied by physicists, engineers, geophysicists and astrophysicis…
