Turbulence中的动态多尺度算法

Dynamic Multiscaling in Turbulence

Rahul Pandit, Samriddhi Sankar Ray, Dhrubaditya Mitra

摘要:

我们给出了一个概述的进展,近年来已取得的理解均匀,各向同性湍流和相关问题的动态多尺度。我们强调这个问题与临界点附近的时间相关关联函数的动态缩放的相似性,例如,旋转系统。通过对流体湍流GOY壳模型的详细模拟,探讨了流体湍流动力学多尺度指数的普遍性。

英文摘要:

We give an overview of the progress that has been made in recent years in understanding the dynamic multiscaling of homogeneous, isotropic turbulence and related problems. We emphasise the similarity of this problem with the dynamic scaling of time-dependent correlation functions in the vicinity of a critical point in, e.g., a spin system. The universality of dynamic-multiscaling exponents in fluid turbulence is explored by detailed simulations of the GOY shell model for fluid turbulence.
