论文摘要
使用直接数值模拟的结果研究了从确定性的雷利数字增加(从$ 10^4 $到$ 10^8 $)的雷利 - 贝纳德对流中的雷利数(从$ 10^4 $到$ 10^8 $)的过渡。已经简要讨论了这种方法在旋转雷利 - 贝纳德对流,稳定分层的流以及大气和太阳光球中观察的应用。
The transition from deterministic to distributed chaos/turbulence at the increase of Rayleigh number (from $10^4$ to $10^8$) in Rayleigh-Bénard convection, controlled by generalized Birkhoff-Saffman invariant, has been studied using the results of direct numerical simulations. The applications of this approach to rotating Rayleigh-Bénard convection, to stably stratified flows, and to observations in the atmosphere and in the solar photosphere have been briefly discussed.
