Navier-Stokes方程的变分方法

A variational approach to Navier-Stokes

Michael Ortiz, Bernd Schmidt, Ulisse Stefanelli

摘要:

本文利用稳定化的加权惯性耗散能(WIDE)泛函给出了不可压Navier-Stokes方程的变分解。这些参数依赖泛函的最小化对应于系统的椭圆时间正则化。通过沿着WIDE极小化器的连续性传递正则化参数的极限,可以恢复经典的Leray-Hopf弱解。

英文摘要:

We present a variational resolution of the incompressible Navier-Stokes system by means of stabilized Weighted-Inertia-Dissipation-Energy (WIDE) functionals. The minimization of these parameter-dependent functionals corresponds to an elliptic-in-time regularization of the system. By passing to the limit in the regularization parameter along subsequences of WIDE minimizers one recovers a classical Leray-Hopf weak solution.
