Ultimate regimes in horizontal and internally heated convection
Olga Shishkina, Detlef Lohse
We derive asymptotic models for the ultimate regimes in horizontal convection (HC) and pure internally heated convection (IHC), in analogy with our recent (2024) extension of the u…
Ultimate regime of Rayleigh-Benard turbulence: Sub-regimes and their scaling relations for Nu vs. Ra and Pr
Olga Shishkina, Detlef Lohse
We offer a new model for the heat transfer and the turbulence intensity in strongly driven Rayleigh-Benard turbulence (the so-called ultimate regime), which in contrast to hitherto…
Scaling relations for heat and momentum transport in sheared Rayleigh-Bénard convection
Guru Sreevanshu Yerragolam, Christopher J. Howland, Richard J. A. M. Stevens +3
We provide scaling relations for the Nusselt number and the friction coefficient in sheared Rayleigh-Bénard convection, i.e., in Rayleigh-Bénard flow with Couette or…
Wall modes and the transition to bulk convection in rotating Rayleigh-Bénard convection
Xuan Zhang, Philipp Reiter, Olga Shishkina +1
We investigate states of rapidly rotating Rayleigh-Bénard convection in a cylindrical cell over a range of Rayleigh number and Ekman number…
