Cryogenic Rayleigh-Bénard convection at Rayleigh numbers above 1e11 (GPP203/12/P897)

number Pr oforder unity) is commonly believed to lay in the range of Rayleigh numbers of the so-called ultimate regime of Rayleigh-Bénard convection, but any generally number via the Nu(Ra,Pr) dependence,...

Non-Oberbeck-Boussinesq effects in turbulent convection in cryogenic helium at high Rayleigh numbers (GC21-06012J)

Experiments on turbulent Rayleigh-Bénard convection (RBC) in cryogenic helium gas reach the highest possible Rayleigh numbers generating vigorous turbulence and momentum in natural systems. However, the high Rayleigh
