Short Note: The ellipticity of Rayleigh waves at infinite depth [PDF]

Geofísica Internacional, 2008
I present an analytical formula and an approximation for the ellipticity of Rayleigh waves in a homogeneous half-space at infinite depth in terms of Poisson’s ratio. The result is compared with the corresponding formulas for surface ellipticity.

Attenuated leaky Rayleigh waves [PDF]

The Journal of the Acoustical Society of America, 1993
The propagation of leaky Rayleigh waves under the influence of viscous damping and heat conduction in boundary layers is studied using the matched asymptotic method. Viscosity of the fluid is considered unimportant except in a thin viscous boundary layer at the interface.

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Detection of standing internal gravity waves in experiments with convection over a wavy heated wall

, 2020
Convection over a wavy heated bottom wall in the air flow has been studied in experiments with the Rayleigh number $\sim 10^8$. It is shown that the mean temperature gradient in the flow core inside a large-scale circulation is directed upward, that ...

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, EarlyView.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Acoustic Wave Propagation In A Fluid-Filled Borehole With A Horizontal Fracture [PDF]

, 1990
The propagation of guided waves in a fluid-filled borehole with an open horizontal fracture is investigated both theoretically and experimentally. The fracture is modeled as a fluid layer that separates the domain of propagation into two regions.

Magneto-thermoelastic surface waves phenomenon with voids, gravity, initial stress, and rotation under four theories

Alexandria Engineering Journal
This paper addresses a significant research gap in the study of surface waves propagation in a nonhomogeneous, within a magneto-thermoviscoelastic material of higher order, initial stress, rotation, gravity effects and voids.
