Suppression of flow reversals via manipulating corner rolls in plane Rayleigh–Bénard convection

Abstract: In this paper, we report that reversals of the large-scale circulation in two-dimensional Rayleigh–Bénard (RB) convection can be suppressed by imposing sinusoidally distributed heating to the bottom plate. We examine how the frequency of flow reversals depends on the dimensionless wavenumber $k$ of the spatial temperature modulation with various modulation amplitude $A$ . For sufficiently large $k$ , the flow reversal frequency i… Show more

“…Nevertheless, EC and thermal convection are two intrinsically different flows (where Rayleigh-Bénard convection (RBC) is now taken as representative of thermal convection). There is a nonlinear external force, caused by the coupling of the electric field and charge distribution in EC whereas the buoyancy in RBC is a kind of linear external force (Castellanos 1991;Zhao & Wang 2017;Zhao 2022). The bifurcation of EC is subcritical (Atten & Lacroix 1978, 1979 while that of RBC is supercritical.…”

“…Numerical studies by Mao (2021Mao ( , 2022 have delved into details of the variations of plate motion with plate size and the underlying mechanism. In addition to the aforementioned set-up, investigations on turbulent convection based on non-uniform thermal boundary conditions have also been considered in recent years (Bakhuis et al 2018;Nandukumar et al 2019;Ostilla-Mónico & Amritkar 2020;Bassani et al 2022;Zhao et al 2022). For example, Zhao et al (2022) numerically investigated the 2-D RBC by applying sinusoidally distributed heating to the bottom plate and Ostilla-Mónico & Amritkar (2020) simulated the 3-D RBC with a top cold plate having a mixture of adiabatic and isothermal boundary conditions.…”
