湍流(turbulence),又称紊流,在美国克雷数学研究院给出的千禧年七个数学难题中是以纳维-斯托克斯方程(Navier-Stokes equations)的形式描述的。以下是Clay Mathematics Institute给出的关于该方程的描述,对解决该问题的一些有意义的方案或思路或许就可以得到解决这一问题的殊荣。 Waves follow our boat as we meander across the lake, and turbulent air currents follow our flight in a modern jet. Mathematicians and physicists believe that an explanation for and the prediction of both the breeze and the turbulence can be found through an understanding of solutions to the Navier-Stokes equations. Although these equations were written down in the 19th Century, our understanding of them remains minimal. The challenge is to make substantial progress toward a mathematical theory which will unlock the secrets hidden in the Navier-Stokes equations. 有兴趣可参见维基百科,关于湍流或纳维-斯托克斯方程的描述。。。
