Abstract

Convection in a layer heated from below and rotating about a vertical axis exhibits a unique phenomenon in fluid dynamics in that the small-amplitude motion is governed by random effects in both its spatial and its time dependence. A simple theoretical description of the phenomenon is compared with laboratory observations. A more detailed mathematical description appears to be feasible because of the weakly nonlinear nature of the problem.

摘要

在一个从下方加热并绕垂直轴旋转的层中的对流，在流体动力学中呈现出一种独特现象，即小振幅运动在其空间和时间相关性上均受随机效应支配。将该现象的一个简单理论描述与实验室观测结果进行了比较。由于该问题的弱非线性性质，更详细的数学描述似乎是可行的。
