Aerodynamic balances are employed in wind tunnels to estimate the forces and moments acting on the model under test. This paper proposes a methodology for the assessment of uncertainty in the calibration of an internal ...

An experimental study of the turbulent wake of a wind turbine model was realized at the “Joaquim Blessmann” wind tunnel of the UFRGS. The turbine model was developed at the Universidade de Caxias do Sul and it represents ...

Wind eroded sediment is sorted by height by both size and density. Less information is available about the elemental composition and enrichment ratios of these sediments. Because of that, the concentration of elements in ...

The soil water content is one of the main factors influencing the beginning of soil particle movement by the wind. Although, some authors studied the effect of soil water content on threshold wind velocity and have defined ...

Although several kinds of energy generation systems have been investigated and introduced in Costa Rica, none were made on systems that use more than one energy source. The present work proposes a safety design of a hybrid ...

This paper discusses some features and conditions that characterize the Zonda wind, focusing particularly on the implications for wind engineering applications. This kind of wind, typical of mountainous regions, is far ...
