Non-normal weakly nonlinear analysis: asymptotic consistency and non-universality
Matthew McCormack, Gregory P. Chini, Rich R. Kerswell
Non-normality can induce large transient growth in linearly stable systems. Determining whether this growth triggers a transition in the underlying nonlinear system, however, requi…
Aspect-ratio-dependent heat transport by baroclinic acoustic streaming
Jacques Abdul Massih, Remil Mushthaq, Guillaume Michel +1
Standing acoustic waves have been known to generate Eulerian time-mean 'streaming' flows at least since the seminal investigation of Lord Rayleigh in the 1880s. Nevertheless, a rec…
Numerical validation of scaling laws for stratified turbulence
Pascale Garaud, Greg P. Chini, Laura Cope +2
Recent theoretical progress using multiscale asymptotic analysis has revealed various possible regimes of stratified turbulence. Notably, buoyancy transport can either be dominated…
Following marginal stability manifolds in quasilinear dynamical reductions of multiscale flows in two space dimensions
Alessia Ferraro, Gregory P. Chini, Tobias M. Schneider
A two-dimensional extension of a recently developed formalism for slow-fast quasilinear (QL) systems subject to fast instabilities is derived. Prior work has demonstrated that the…
Steady Rayleigh--Bénard convection: strongly nonlinear high-wavenumber rolls
Baole Wen, Alexander Takla, David Goluskin +1
In Rayleigh--Bénard convection, two-dimensional steady rolls bifurcate supercritically at a Rayleigh number that depends on their horizontal-to-vertical aspect ratio , and…
Multiple scales analysis of slow--fast quasilinear systems
G. Michel, G. P. Chini
This article illustrates the application of multiple scales analysis to two archetypal quasilinear systems; i.e. to systems involving fast dynamical modes, called fluctuations, tha…
