New concept to improve power production of wind turbines

Hui Hu, professor of aerospace engineering, and his group at Iowa State University studied the effects of the relative rotation directions of two tandem wind turbines on the power production performance, the flow characteristics in the turbine wake flows, and the resultant wind loads acting on the turbines. The experimental study was performed in a … Continue reading New concept to improve power production of wind turbines

Iowa State engineers study how hills, nearby turbines affect wind energy production

Hui Hu pulled a model wind turbine from the top of an office filing cabinet. The turbine tower was just 10 inches high. Its three blades were 10 inches in diameter. It was a perfect 1:320 scale reproduction of the 80-meter diameter wind turbines spinning across Iowa, the country’s second-ranked state in installed wind power capacity. That … Continue reading Iowa State engineers study how hills, nearby turbines affect wind energy production
