2022 MAY 12 (NewsRx) -- By a News Reporter-Staff News Editor at Energy Daily News -- Data detailed on Energy - Wind Turbines have been presented. According to news reporting out of Shiraz, Iran, by NewsRx editors, research stated, “Sustainability and more power generation are vast crucial issues in the commercialization of vertical axis wind turbines specifically for small-scale and urban applications. Savonius rotors are an attractive kind of turbine compared to other wind turbines due to their simple design and self-starting capability.”

Our news journalists obtained a quote from the research from the Shiraz University of Technology, “However, these types of turbines have low performance in terms of power generation. This study employs a wind accelerator called ‘wind-lens’ for Savonius wind turbine in single-rotor and twin-rotor configurations to harness more viable energy even in the low-speed region. The results of the present study can help designers and scientists to interpret the effective parameters of the proposed system for further development. High-fidelity numerical simulations are performed to investigate operational parameters like tip speed ratio and geometric parameters such as the rotational direction and position of the rotors within the wind-lens. Also, using the pressure and velocity contours along with the streamlines, an attempt is made to describe the power improvement by the proposed system.”

According to the news editors, the research concluded: “The results show that a twin-rotor ducted turbine in the optimal point can improve the maximum power coefficient of the system by about 114% relative to an open turbine.”

This research has been peer-reviewed.
