While the Cartesian equations seem to follow directly from the vector equation above, the vector form of the Navier–Stokes equation involves some tensor calculus which means that writing it in other coordinate systems is not as simple as doing so for scalar equations (such as the heat equation...

and the momentum (Navier-Stokes) equation (2)DuDt=−∇p+1Re∇2u The equations are written in vector form (from here on, boldface type symbols denote vector or matrix quantities). The variables are non-dimensionalized using a reference velocity and a characteristic length, as usual. Re ...
Thus the governing equation is an integro-differential equation and not convenient for numerical computation. An equivalent weak or variational form of the equation, proved to produce the same velocity solution as the Navier–Stokes equation,[18] is given by, for divergence-free test functions ...
Cauchy momentum equation (conservation structure) \(\begin{array}{l}\rho \frac{Du}{Dt} = -\bigtriangledown p + \bigtriangledown \cdot \tau + \rho g\end{array} \) Every non-relativistic balance equation, such as the Navier–Stokes equations, can be constructed by starting with the Cauc...
We study the solutions of the nonstationary incompressible Navier–Stokes equations in , of self-similar form , obtained from small and homogeneous initial data a(x). We construct an explicit asymptotic formula relating the self-similar profile U(x) of the velocity field to its corresponding init...

先来总结一下Navier-Stokes方程的解适定性问题研究的历史。 此方程适定性研究之滥觞,应是Lerry的[1]这篇法文文献。这篇文献很长有英文的翻译版本。这篇文章告诉我们有限能量的初值(L^2)存在至少一个全局弱解,且该弱解满足能量不等式。其中弱解就是在弱意义下满足方程的解,满足能量不等式的弱解,也叫做Leray弱...
