This theory can be used to determine the forces, flow velocities, and power of a rotor, whether that rotor is extracting energy from the airflow, as in a wind turbine, or applying energy to the flow, ...

In this paper a new method based on blade element theory is described, aiming at the calculation of the characteristics of a wind rotor and the analysis of its aerodynamic behaviour. The new method ...

A new study develops a theory of how magnetic switchbacks are formed around the sun. This quantitative model can be used to predict magnetic field variations and potentially explain the heating and ...

Wind Engineering, Vol. 39, No. 3 (2015), pp. 271-298 (28 pages) ABSTRACT When developing a wind farm, it is very important to accurately define the wind resource distribution across the project area ...

In a long-awaited, historic step toward “real" not cookbook wind engineering, the Structural Engineering Institute of the American Society of Civil Engineers recently issued a recommended alternative ...

Rainier Square Tower, under construction in Seattle, is one of the buildings considered for the development of a performance-based wind design manual for tall buildings. Photo Courtesy of ...

The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these ...
