Flow reversals in thermally driven turbulence
Kazuyasu Sugiyama, Rui Ni, Richard J. A. M. Stevens +7
We analyze the reversals of the large scale flow in Rayleigh-Bénard convection both through particle image velocimetry flow visualization and direct numerical simulations (DNS) of…
Oscillations of the large-scale circulation in turbulent Rayleigh-Bénard convection: the off-center mode and its relationship with the torsional mode
Quan Zhou, Heng-Dong Xi, Sheng-Qi Zhou +2
We report an experimental study of the large-scale circulation (LSC) in a turbulent Rayleigh-Bénard convection cell with aspect ratio unity. The temperature-extremum-extraction (TE…
Origin of the Temperature Oscillation in Turbulent Thermal Convection
Heng-Dong Xi, Sheng-Qi Zhou, Quan Zhou +2
We report an experimental study of the three-dimensional spatial structure of the low frequency temperature oscillations in a cylindrical Rayleigh-Bénard convection cell. It is fou…
Measured oscillations of the velocity and temperature fields in turbulent Rayleigh-Bénard convection in a rectangular cell
Sheng-Qi Zhou, Chao Sun, Ke-Qing Xia
Temperature and velocity oscillations have been found in a rectangular Rayleigh-Bénard convection cell, in which one large scale convection roll exists. At …
Fluctuations of a homeotropically aligned nematic liquid crystal in the presence of an applied voltage
Sheng-Qi Zhou, Guenter Ahlers
We determined the refractive-index structure-factor from shadowgraphs of fluctuations in a layer of a homeotropically aligned nematic liquid crystal with negative diel…
