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 $Ra$ that depends on their horizontal-to-vertical aspect ratio $\Gamma$, and…
