振荡剪切流的频谱

The spectra of the oscillating shear flows

Sergey Guda

摘要:

本文研究不可压缩无粘流体空间周期流动的谱问题。所考虑的基本流动是剪切流,其剖面在高频上振荡。对于这样的流,我们提出了渐近展开的不稳定的特征值的情况下,极限谱问题有多个特征值。

英文摘要:

We study the spectral problems for the spatially periodic flows of inviscid incompressible fluid. The basic flows under consideration are the shear flows whose profiles oscillate on high frequencies. For such flows, we present asymptotic expansions of the unstable eigenvalues in the case when the limit spectral problem has multiple eigenvalues.
