Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.

Many of today's scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life data. Providing validation data, using up-to-date methods, was a key motivating factor for a recent experimental study.

A team of researchers performed wind tunnel experiments to determine the role of asymmetry caused by the orientation of a volleyball on its aerodynamic characteristics. They found that switching from the standard panel arrangement to a hexagonal or dimpled pattern may improve the consistency of flight, with many potential applications in aviation.

Overturning tractors are the leading cause of death for farmers around the world. In order to reduce the rate of overturned tractors, researchers have developed a model for understanding the conditions that lead to a tractor overturning from an unlikely source: They based their model on one used to understand the unpredictability of a bouncing ball.

New report deepens understanding of wind-wildlife interactions

An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.
