我们将涡旋动力学定义为研究方程的层流(即非湍流)解
$$\frac{{\Partial\omega}}{{\Partial t}}+u\Bullet\nabla\omega=-\omega\Bullet\nabla u+\Left({v{\nabla^2}\omega}\right)$$
(1)
$$u=cur{L^{-1}}\omega$$
(2)
其中ω是紧凑的。这也暗示通常v≪1。
We shall define Vortex Dynamics to be the study of laminar (i.e. non turbulent) solutions of the equations
$$ \frac{{\partial \omega }}{{\partial t}} + u \bullet \nabla \omega = - \omega \bullet \nabla u + \left( {v{\nabla ^2}\omega } \right) $$
(1)
$$ u = cur{l^{ - 1}}\omega $$

for which ω is compact. It is also implied that usually v ≪ 1.
