摘要翻译:
本文综述了近几年来在认识均匀各向同性湍流的动力学多标度及其相关问题方面所取得的进展。我们强调了这个问题与临界点附近的含时关联函数的动力学标度的相似性,例如自旋系统。通过对流体湍流的GOY壳模型的详细模拟,探讨了动力多标度指数在流体湍流中的普适性。

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.
