Wind turbines represent a growing energy source worldwide. In many cases, operating in turbulent and changing wind direction spots. In this work, we use a wind tunnel to analyse the effect of the turbulence in a wind ...

El objetivo fue medir el efecto de un concentrador de flujo tipo wind lens en el caso de flujo turbulento. El estudio se realizó en el túnel de viento de capa límite del Instituto de Investigación en Mecánica Aplicada de ...

A comparative evaluation of the fatigue damage occurring in the blades of small wind turbines, with different power regulation schemes, has been conducted for the first time. Three representative test cases were built, one ...

Efforts to correct precipitation measurements have been ongoing for decades, but are scarce for tropical highlands. Four tipping-bucket (TB) rain gauges with different resolution that are commonly used in the Andean mountain ...

Tropical and subtropical high-mountain forests are often restricted to ravines, with forest presence being rare in other topographies such as ridges. We tested the hypothesis that this distribution is partly due to increased ...

The release of vast quantities of sulfide from the sediment into the water column, known as a sulfidic event, has detrimental consequences on fish catches, including downstream effects on other linked element cycles. Despite ...

Pollution problems such as the greenhouse effect as well as the high value and volatility of fuel prices have forced and accelerated the development and use of renewable energy sources. In the three last decades, the level ...

The study aims to assess the wind behavior and its effect on the thermal sensation in urban canyons of the historic center of Cuenca. The methodology is based on the selection of case studies of the functional unit of the ...

According to March 18, 2022 data from the Brazilian Wind Energy Association (ABEEólica) the average annual wind power generation supplies about 29 million households per month in Brazil, which corresponds to 86.4 million ...
