The high emission of fossil fuels are major driving forces in renewable energy technology
development. In response, the lift-type vertical axis wind turbines (VAWT) is experiencing a …

Energy use in cities has attracted significant research in recent years. However such a broad
topic inevitably results in number of alternative interpretations of the problem domain and …

Since millenaries humans have attempted to harness the wind energy through diverse
means. Vertical axis wind turbines (VAWTs) were originally considered as very promising …

Unlike horizontal axis wind turbines (HAWTs), the Darrieus vertical axis wind turbine (H-type
VAWT) has been the subject of only a few recent studies directed at improving its self …

Wind tunnel tests were conducted to systematically assess the aerodynamic performance of
both H-rotor and helical vertical axis wind turbines (VAWTs) in smooth and turbulent flows …

Optimizing vertical-axis wind turbine (VAWT) pairs is vital for addressing future energy
needs, given that their power and aerodynamics are notably affected by wake interactions …

Installation of H-type vertical axis wind turbines is in many cases limited by the inherent start-
up issues associated with this type of turbine. This could be crucial in environments with low …

In this study a 3 kW straight–bladed Darrieus type Vertical Axis Wind Turbine (VAWT) is
investigated numerically using OpenFOAM computational fluid dynamic package. The newly …

Wind energy represents a very important source of energy for many countries nowadays.
Wind energy provides an efficient and an effective solution to reduce fusel fuel consumption …

In unfavourable wind conditions, factors such as low wind speed, high turbulence, and
constant wind direction change can reduce the power production of a horizontal axis wind …
