New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight ...
A study into the aerodynamic performance of feathered dinosaurs, by scientists from the University of Southampton, has provided new insight into the evolution of bird flight.
A new computational scheme enables more stable simulations of shockwaves in fluids and may be scalable for large engineering designs.
Interest in developing alternative energy sources is driving the consideration of a promising technology that uses underwater turbines to convert ocean tidal flow energy into electricity.
A milestone in the history of renewable energy occurred in the year 2008 when more new wind-turbine power generation capacity was added in the U.S. than new coal-fired power generation. The costs of producing power with wind ...
A group of Cambridge students are hoping that their game-changing design of solar car will make them the first British winners of the World Solar Challenge.
(Phys.org)—Ever since the Wright brothers, engineers have been working to develop bigger and better flying machines that maximize lift while minimizing drag.
