分数阶波动方程的阻尼及其在水波中的应用

Damping for fractional wave equations and applications to water waves

Thomas Alazard, Jeremy L. Marzuola, Jian Wang

AI总结:

本文研究阻尼分数阶水波线性模型,针对足够正则初值建立并显式给出能量衰减率,在部分模型上首次证明表面波能量衰减。

摘要:

受无粘 Euler 方程表面波数值建模的启发,我们分析了阻尼水波的线性模型,并针对具有足够正则性的初始构型建立了能量的衰减性质。研究结果给出了明确的能量衰减率,但未涉及波在阻尼界面处的反射与透射。尽管如此,对于所考虑模型的一个子集,这仍是首个证明表面波模型能量衰减的结果。

英文摘要:

Motivated by numerically modeling surface waves for inviscid Euler equations, we analyze linear models for damped water waves and establish decay properties for the energy for sufficiently regular initial configurations. Our findings give the explicit decay rates for the energy, but do not address reflection/transmission of waves at the interface of the damping. Still for a subset of the models considered, this represents the first result proving the decay of the energy of the surface wave models.
