Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and maximize ...

In an RL-based control system, the turbine (or wind farm) controller is realized as an agent that observes the state of the ...

Everyone’s owned a pinwheel at one time or another. I remember riding in the back of my parents’ car, sticking my pinwheel out the window as we traveled down the street. The speed at which the ...

Blade pitch control systems enhance the consistency of wind turbines' electrical energy output and ensure that rotor speed remains within a safe operating range by constantly adjusting turbine blades ...

With over 350,000 wind turbines currently in use globally, wind continues to be one of the fastest growing forms of renewable energy. In 2021, 93.6 GW of new installations brought global cumulative ...

Engineers at Purdue University and Sandia National Laboratories have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades.

Each year a panel reviews papers nominated from the past two years and selects an article of high significance. The paper, published in 2022, describes the first experimental implementation of Model ...
