论文摘要
我们考虑以下$ 2+\ frac {1} {2} $ - 尺寸的情况下的3D不可压缩的Navier-Stokes方程：尺寸：垂直涡旋blob（quasi-streamwise涡流）通过二维剪切流延伸。我们证明了这种准过程涡流引起的增强耗散。
We consider the 3D incompressible Navier-Stokes equations under the following $2+\frac{1}{2}$-dimensional situation: vertical vortex blob (quasi-streamwise vortices) being stretched by two-dimensional shear flow. We prove enhanced dissipation induced by such quasi-streamwise vortices.
