Generation of a mountain-valley wind in an atmospheric boundary wind tunnel: a gust-wind generator study

open access: yesAdvances in Bridge Engineering, 2023
AbstractAppropriate modeling of an experimental technology is necessary in order to estimate the aerodynamic characteristic of railway trains and infrastructure (e.g., bridges). Simulation of the earth’s wind characteristics of nature is a well-established practice by using an atmospheric boundary wind tunnel. However, in the mountainous area, the wind

Optimal Operation of a Wind Driven System

open access: yesJournal of King Saud University: Engineering Sciences, 2004
This paper presents a number of controlling techniques that can used in extracting the wind energy from a wind prime mover. The extraction of wind energy bears in mind the target of matching the electric power needed by an electric generator with the ...

WIND-GENERATED LONGSHORE CURRENTS

open access: yesCoastal Engineering Proceedings, 1978
This paper evaluates, through the use of a stepwise multiple regression procedure, whether parameters descriptive of the surf-zone wave field adequately explain the variability in longshore current velocities, or if the inclusion of additional physical environmental parameters could significantly improve the ability to predict such currents.

Generator Systems for Marine Current Turbine Applications: A Comparative Study [PDF]

open access: yes, 2012
Emerging technologies for marine current turbines are mainly related to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the
