Conservation Laws and Bounds on the Efficiency of Wind-Wave Growth [PDF]

open access: yes, 2014
We examine two means by which wind can impart energy to waves: sheltering and deposition of material upwards from windward surface shear. The shear driven deposition is shown to be the more efficient process.

Using wind setdown and storm surge on Lake Erie to calibrate the air-sea drag coefficient.

open access: yesPLoS ONE, 2013
The air-sea drag coefficient controls the transfer of momentum from wind to water. In modeling storm surge, this coefficient is a crucial parameter for estimating the surge height. This study uses two strong wind events on Lake Erie to calibrate the drag

An extended nonlinear Schrödinger equation for water waves with linear shear flow, wind, and dissipation

open access: yesAIP Advances, 2021
Based on potential flow theory, governing equations are developed for surface gravity waves affected by wind, dissipation, and a linear shear flow (LSF). The LSF is composed of a uniform flow and a shear flow with constant vorticity.

Effects of acceleration, frequency and mild motion sickness on continuous tracking task accuracy in response to simulated wind-induced building motion

open access: yesAdvances in Wind Engineering
This study investigates the effects of acceleration, frequency and motion sickness on task performance. Using a mixed factorial design, we exposed 40 participants to a range of sinusoidal accelerations (8 to 30 milli-g), frequencies (0.125 to 1 Hz) and ...

Wave-Slope Soaring of the Brown Pelican [PDF]

open access: yes, 2019
We theoretically assess the energy savings associated with wave-slope soaring of the brown pelican over near-shoaling ocean surface waves. The steady, constant altitude flight of a pelican is analyzed as a control.

Paper waves in the wind

open access: yes, 2015
A flexible sheet clamped at both ends and submitted to a permanent wind is unstable and propagates waves. Here, we experimentally study the selection of frequency and wavenumber as a function of the wind velocity.

The Impact of Sea State Condition on Airborne Lidar Bathymetry Measurements [PDF]

open access: yes, 2012
Due to a large number of available Airborne Lidar Bathymetry (ALB) survey datasets and scheduled future surveys, there is a growing need from coastal mapping communities to estimate the accuracy of ALB as a function of the survey system and environmental

Standing waves in the plenum of an open jet wind tunnel: Resonance and self-excited oscillation

open access: yesAIP Advances, 2022
The low-frequency pressure pulsations in a large low-speed open jet wind tunnel were studied using a 1:20 scaled model wind tunnel. It was found that plane pressure standing waves existed in all three directions of the wind tunnel’s plenum.

Predicting Wind Wave Suppression on Irregular Long Waves

open access: yesJournal of Marine Science and Engineering, 2020
The applicability of the wind wave suppression model developed by Chen and Belcher (2000) to irregular wave environments is investigated in this study. Monochromatic and irregular wave environments were simulated in the W2 (Wind/Wave) laboratory at the ...

Interaction of suprathermal solar wind electron fluxes with sheared whistler waves: fan instability [PDF]

open access: yesAnnales Geophysicae, 2003
Several in situ measurements performed in the solar wind evidenced that solar type III radio bursts were some-times associated with locally excited Langmuir waves, high-energy electron fluxes and low-frequency electrostatic and electromagnetic ...
