查询词典 fluid dynamics

And this is where Lagrange comes in. He was a pioneer of the study of moving fluids, but his ideas outran the computational tools of his day. Only now, with supercomputers available to help with the calculations, is it possible to explore those ideas completely. What is emerging is a picture of fluid dynamics more subtle and more complex than anything dreamed of even a decade ago.

这正是Lagrange所研究的，他是流体运动学的创始人，但是他的思想已经超出了他那个年代的计算能力，只有在今天，通过现有的超级计算机的计算去探究他们的这些思想才是有可能的，浮现出来是一幅流体动态变化的图像，其细微和复杂程度是十年前无论如何也想不到的。

Nigel Goldenfeld, shows how scaling ideas and RG concepts may be applied not only to continuous phase transitions, such as ferromagnetism to paramagnetism, but also to far from equilibrium phenomena, such as nonlinear diffusion in fluid dynamics, which can be described by the classical partial differential equations.

Goldenfeld指出标度和重整化群的概念不仅仅可以应用到一些我们熟知的现象上面，如铁磁到顺磁的相变，而且可以应用到远离平衡态的现象，这些现象是可以用经典的偏微分方程来描述的，例如流体的非线性扩散。
