Rayleigh-benard thermal convection

WebAug 8, 2024 · 2D steady state solution of coupled momentum, continuity and energy equations. The fluid is driven by the Rayleigh–Bénard convection. WebAug 7, 2024 · Here we reveal such features in three different types of Rayleigh-Bénard (RB) convection, i.e., buoyancy-driven flow with the fluid density being affected by a scalar field. In the three cases different stabilizing forces are considered, namely (i) horizontal confinement, (ii) rotation around a vertical axis, and (iii) a second stabilizing scalar field.
