One often overlooked aspect of VAWT blade design is the self-starting ability. VAWTs generally are poor in this regard. The Darrieus and certain Gorlow designs are difficult to design well.

This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator.The whole ...

However, the performance of VAWTs is lacking compared to HAWTs due to low turbine efficiency at downstream caused by large wake vortices generated by advancing blades in the upstream position.

The development of the vertical-axis wind turbine (VAWT ... are some design features that prevent the generators from functioning as well as HAWTs at harvesting energy. The blades don’t produce ...

The team suggests two pitch profiles for VAWT blades that result in a 200 percent ... identify optimal pitching kinematics at on- and off-design operating conditions. We obtain two sets of optimal ...

Reporting in the journal Thermal Engineering, researchers from the Moscow Power Engineering Institute have now developed a parameter-driven optimization approach to blade design that makes sense ...

Engineers have long known that traditional aerodynamics models, used to design the blades of wind turbines and propellers, ...

In South Carolina’s Lowcountry, artists, farmers and designers are writing a new chapter in indigo’s rich and tangled history. By Patricia Leigh Brown In Brandon Ndife’s otherworldly ...

The machine simply feels well built. Despite all that the Razer Blade 16 is packing in, it still feels like a more everyday laptop thanks to the subtle design. It slides right into my backpack ...
