Title: On the Rayleigh–Bénard convection problem for rotating fluids.
Authors: Fanelli, Francesco1,2,3 (AUTHOR) ffanelli@bcamath.org, Feireisl, Eduard4 (AUTHOR)
Source: Geophysical & Astrophysical Fluid Dynamics. Apr2026, Vol. 120 Issue 2, p88-121. 34p.
Subjects: Rotating fluid, Navier-Stokes equations, Rayleigh-Bénard convection, Thermal gradient measurment, Gravity, Buoyancy-driven flow, Buoyancy, Centrifugal force
Abstract: In contrast with a large variety of conventional models of thermally driven fluids, we show that the standard Oberbeck–Boussinesq approximation cannot be obtained as a singular limit of the Navier–Stokes–Fourier system in the rotational coordinate system, with the buoyancy force proportional to the sum of the gravitational and centrifugal forces multiplied by the temperature variation.
