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 $Ra=8.9\times 10^{11}$…
