Vent holes can be used to reduce the aerodynamic pressure loads on nonstructural elements of buildings. The analysis of these loads applied on nonstructural elements of buildings (window panes, closure panels, etc.) with vent holes, under... more
A state-of-art wind mapping system, the Wind Energy Simulation Toolkit (WEST), was developed in the Meteorological Service of Canada (MSC) for use by the wind energy industry. WEST is based on a statistical-dynamical downscaling approach,... more
This work demonstrates a technique to identify information about the ice mass accumulation on wind turbine blades using its natural frequencies, and these frequencies reduce differently depending on the spatial distribution of ice mass... more
In this paper, the objective of this study is to evaluate the wind potential of the site Sidi Daoud, at 30m height above ground level, by three statistical methods (meteorological, Weibull and Rayleigh), to identify the characteristic... more
Wind characteristics and wind turbines characteristics in Sidi Daoud site, Tunisia, have been thoughtfully analyzed based on a measured data source during the year 2004 at heights of 45, 50 and 60m above ground in two places (Mast 1 and... more
Since ancient times, Architecture have always been an environment sensitive field in their design approach which makes it deal with various obstacles present in the nature. The study of local climatic characteristics navigates the... more
Este trabalho apresenta por meio de revisão bibliográfica as vantagens e desvantagens das redes centralizadas e descentralizadas de distribuição de energia eólica, principalmente no que se refere aos aspectos socioeconômicos, ambientais e... more
Le but de ce papier est de constituer une base de données aux utilisateurs de l'énergie éolienne en Tunisie. Il présente l' étude de dix-sept sites synoptiques distribués sur tout le territoire tunisien. A partir des données... more
The purpose of this paper is to constitute a database for the users of the wind power. It presents the study of 17 synoptic sites distributed on all the territory of Tunisia. From the meteorological data provided by the Meteorology... more
Commercial production greenhouses are widely used to produce plants and crops. From the structural engineering viewpoint, among the loads that act on greenhouses, wind and snow loads are the major ones. This paper focuses on the former,... more
Nigeria is ranked among the lowest countries in terms of per capita energy consumption in the world. It also produces significant CO2 emissions. Hence, there is a vital need for clean and accessible energy in the country. Wind energy... more
Este artículo presenta un modelo estocástico para la simulación del comportamiento de la velocidad del viento en dirección horizontal. Además, se desarrollan modelos tanto para grandes como pequeñas escalas de tiempo. Estos modelos se... more
Wind damage to asphalt shingles is usually obvious. However, there remain a number of issues such as cupping, splitting, and lack of bonding which some people falsely attribute to wind. This paper discusses what wind damage is and is... more
In wind load calculations based on pressure measurements, the concept of 'tributary area' is usually used. The literature has less guidance for a systematic computational methodology for calculating tributary areas, in general, and for... more
Edificações em geral estão submetidas a carregamentos de vento, que variam de acordo com alguns fatores de exposição. Tais fatores devem ser considerados na fase de projetos, para alcançar bons níveis de segurança e confiabilidade... more
This interactive qualifying project focused on the ever advancing hybrid vehicle technology and its integration with wind energy. The main objective of this project is to design and fabricated a self-starting small vertical axis wind... more
A series of wind tunnel tests were performed to investigate the effect of turbulent inflows on the aerodynamic characteristics of variously modified leading-edge protuberanced (LEP) wing configurations at various turbulence intensities. A... more
