Effect of the Earth's Coriolis force on the large-scale circulation of turbulent Rayleigh-Bénard convection
2006
Physics of Fluids
We present measurements of the large-scale circulation ͑LSC͒ of turbulent Rayleigh-Bénard convection in water-filled cylindrical samples of heights equal to their diameters. The orientation of the LSC had an irregular time dependence, but revealed a net azimuthal rotation with an average period of about 3 days for Rayleigh numbers R տ 10 10 . On average there was also a tendency for the LSC to be aligned with upflow to the west and downflow to the east, even after physically rotating the
