Developing wind projects in complex terrain using wind software

Archived; click post to view.
Excerpt: The emergence of software and science can turn even complex terrain into productive wind farms. As potential sites with simple, flat terrain are developed, more wind projects are built in or near forests and complex terrain. These sites—associated with harsh flow conditions—are likely t …

Simulation Software: Software finds a blade profile with 48% more lift

Archived; click post to view.
Excerpt: T he aerodynamic shape of wind- turbine blades generates lift and torque, which is eventually turned into electrical power. Improving a blade’s shape so it captures just a percent or two more would be a significant improvement. One such redesign project shows how Computational Fluid Dynamics (CFD) …
