白噪声作用下的边界涡换热turbulence

Eddy heat exchange at the boundary under white noise turbulence

Franco Flandoli, Lucio Galeati, Dejun Luo

摘要:

我们证明了一个理想化的湍流模型的涡流热扩散系数的存在。困难在于存在边界,在边界处还有湍流混合和涡流扩散系数趋于零。尽管如此,还是发生了增强的扩散。

英文摘要:

We prove the existence of an eddy heat diffusion coefficient coming from an idealized model of turbulent fluid. A difficulty lies in the presence of a boundary, with also turbulent mixing and the eddy diffusion coefficient going to zero at the boundary. Nevertheless enhanced diffusion takes place.
