非齐次Muskat问题的整体结果

Global Results for the Inhomogeneous Muskat Problem

Neel Patel, Nikhil Shankar

摘要:

非均匀马斯卡特问题模拟了非均匀多孔介质中两种不同特性流体之间的界面动力学。我们考虑的情况下,多孔介质的渗透率跨越水平边界远离两个不同的粘度和密度的流体之间的界面跳跃。对于显式介质尺寸的初始数据,根据流体和多孔介质的特性,我们将证明解的整体存在性和唯一性,该解是瞬时解析的,并随时间衰减到平坦界面。

英文摘要:

The inhomogeneous Muskat problem models the dynamics of an interface between two fluids of differing characteristics inside a non-uniform porous medium. We consider the case of a porous media with a permeability jump across a horizontal boundary away from an interface between two fluids of different viscosities and densities. For initial data of explicit medium size, depending on the characteristics of the fluids and porous media, we will prove the global existence and uniqueness of a solution which is instantly analytic and decays in time to the flat interface.
