Universal fluctuations in the bulk of Rayleigh-Bénard turbulence

Yi-Chao Xie, Bu-Ying-Chao Cheng, Yun-Bing Hu +1

We present an investigation of the root-mean-square (rms) temperature ${\sigma }_T$ and the rms velocity ${\sigma }_w$ in the bulk of Rayleigh-Bénard turbulence, using new experimental data from t…
