Effect of Periodic Bottom Plate Heating on Large Scale Flow in Turbulent Rayleigh-Bénard Convection
We report analysis of temperature fluctuations measured inside a Rayleigh-Bénard convection cell of aspect ratio unity with steady and time-varying heating of the bottom boundary. The working fluid is cryogenic helium gas at Rayleigh number Ra = 1013, for which a large scale coherent flow (mean wind...
