Wind conditions in the built environment are complex in nature and characterized by lower
wind speeds and higher turbulence due to the presence of obstructions. A growing body of …

The increasing global demand for energy and environmental concerns have provoked a
shift from exhaustible, fossil fuel based energy to renewable energy sources. It is clear that …

The right location of an individual wind turbine within a wind farm is important in order to
gain its optimal power output. Due to the large area involved, an experimental study can be …

In aircraft, the main landing gear wheels skid on the runway at the moment of touchdown
because of high slip. A slip** tyre generates enough heat to melt its rubber. Melted rubber …

A combination of climate change, due to anthropogenic CO2 emissions and concerns over
energy security, due to fluctuating fuel prices, has led to the UK pushing to increase its …

O presente trabalho apresenta um estudo numérico e experimental sobre o desempenho
aerodinâmico de turbinas eólicas de eixo vertical envolvendo rotores Savonius …

Proper arrangement of multiple VAWT turbines has been known to have increased the
overall power efficiency. The challenge is how to optimally place each turbine within a given …

The Savonius turbine is a type of vertical wind turbine with a simple design and is easy to
manufacture. This turbine has two semicircular blades that rotate in opposite directions …

The chapter presents a numerical simulation of a three‐dimensional, non‐stationary flow in
a Savonius, vertical‐axis wind turbine. It develops a computational code for solving the …

This article presents a kind of apologetics for cross-flow wind machines. At the beginning,
general knowledge and initial stages of development for S-type rotors are described. The …
