Geometry-dependent Ekman layer approximations on curved domains: L^{\infty} convergence
Yifei Jia, Yi Du, Lihui Guo
The Ekman boundary layer is a fundamental concept in fluid dynamics that describes fluid motion near boundaries affected by Earth's rotation. Most theoretical studies have simplifi…

Non-flat Ekman Boundary Layers: Topographic Lift, Generalized Ekman Pumping, and Anisotropic Asymptotic Behavior
Yifei Jia, Yi Du, Lihui Guo
The Ekman boundary layer, a fundamental concept in geophysical fluid mechanics, describes the near-boundary fluid motion subject to rotation. Within the singular limit framework of…

The Vanishing Pressure Limits of Riemann Solutions to the Chaplygin Euler Equations
Gan Yin, Chun Shen, Lihui Guo
The Riemann solutions to Chaplygin Euler equations with a scaled pressure are considered. When the pressure vanishes, there are three cases. The Riemann solution containing two sho…
