Effects of polymer additives in the bulk of turbulent thermal convection
Yi-Chao Xie, Shi-Di Huang, Denis Funfschilling +3
We present experimental evidence that a minute amount of polymer additives can significantly enhance heat transport in the bulk region of turbulent thermal convection. The effects…
Heat transport by turbulent Rayleigh-Bénard convection for $\Pra\ \simeq 0.8$ and $4\times 10^{11} \alt \Ra\ \alt 2\times10^{14}$: Ultimate-state transition for aspect ratio
Xiaozhou He, Denis Funfschilling, Eberhard Bodenschatz +1
We report experimental results for heat-transport measurements by turbulent Rayleigh-Bénard convection in a cylindrical sample of aspect ratio ( m is…
Heat transport by turbulent Rayleigh-Bénard convection for $\Pra\ \simeq 0.8$ and $3\times 10^{12} \alt \Ra\ \alt 10^{15}$: Aspect ratio
Guenter Ahlers, Xiaozhou He, Denis Funfschilling +1
We report experimental results for heat-transport measurements, in the form of the Nusselt number \Nu, by turbulent Rayleigh-Bénard convection in a cylindrical sample of aspect rat…
Logarithmic temperature profiles in turbulent Rayleigh-Bénard convection
Guenter Ahlers, Eberhard Bodenschatz, Denis Funfschilling +5
We report results for the temperature profiles of turbulent Rayleigh-Bénard convection (RBC) in the interior of a cylindrical sample of aspect ratio ( and $…
Search for the "ultimate state" in turbulent Rayleigh-Bénard convection
Denis Funfschilling, Eberhard Bodenschatz, Guenter Ahlers
Measurements of the Nusselt number and of temperature variations in the bulk fluid are reported for turbulent Rayleigh-Bénard convection of a cylindrical sample. They c…
Enhanced heat transport by turbulent two-phase Rayleigh-Bénard convection
Jin-Qiang Zhong, Denis Funfschilling, Guenter Ahlers
We report measurements of turbulent heat-transport in samples of ethane (CH) heated from below while the applied temperature difference straddled the liquid-vapor co-e…
