Thermal Waves and Heat Transfer Efficiency Enhancement in Harmonically Modulated Turbulent Thermal Convection
P. Urban, P. Hanzelka, T. Králík +2
We study turbulent Rayleigh-Bénard convection over four decades of Rayleigh numbers 4E8 < Ra < 2E12, while harmonically modulating the temperatures of the plates of our cylindrical…
Effect of boundary conditions in turbulent thermal convection
P. Urban, T. Králík, M. Macek +2
We report an experimental study aiming to clarify the role of boundary conditions (BC) in high Rayleigh number turbulent thermal convection of…
Thermal Radiation in Rayleigh-Bénard Convection Experiments
P. Urban, T. Králík, P. Hanzelka +4
An important question in turbulent Rayleigh-Bénard convection (RBC) is the effectiveness of convective heat transport, which is conveniently described via the scaling of the Nussel…
Mass of Abrikosov vortex in high-temperature superconductor YBaCuO
Roman Tesar, Michal Sindler, Christelle Kadlec +3
Mass of Abrikosov vortices defied experimental observation for more than four decades. We demonstrate a method of its detection in high-temperature superconductors. Similarly to el…
Intermittency enhancement in quantum turbulence
Emil Varga, Jian Gao, Wei Guo +1
Intermittency is a hallmark of turbulence, which exists not only in turbulent flows of classical viscous fluids but also in flows of quantum fluids such as superfluid He. Despi…
Quantum Turbulence of Bellows-Driven 4He Superflow: Decay
Simone Babuin, Emil Varga, William F. Vinen +1
We report on studies of quantum turbulence with second-sound in superfluid 4He in which the turbulence is generated by the flow of the superfluid component through a wide square ch…
