摘要翻译:
我们回顾了高维超统计随机模型的一些性质。作为一个例子,我们分析了一个三维拉格朗日湍流超统计模型的随机性质,并与实验数据进行了比较。对于加速度概率密度、拉格朗日标度指数、加速度分量之间的关联以及关联的时间衰减等测量量,都得到了很好的一致性。我们评论如何从超统计继续到热力学描述。

英文摘要:
  We review some of the properties of higher-dimensional superstatistical stochastic models. As an example, we analyse the stochastic properties of a superstatistical model of 3-dimensional Lagrangian turbulence, and compare with experimental data. Excellent agreement is obtained for various measured quantities, such as acceleration probability densities, Lagrangian scaling exponents, correlations between acceleration components, and time decay of correlations. We comment on how to proceed from superstatistics to a thermodynamic description.
