As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And wind has long served as a power source to humans. Ancient mariners used sails to capture ...

A computer simulation of air flow through a turbine found that ... “Another perspective is that winglets enable turbines to capture more wind energy by minimising losses [resistance],” says ...

Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris.

The researchers installed sensors on an actuating blade shaft to assess the air forces ... the flow structures to enhance performance. Our results can aid vertical-axis wind turbines increase ...

French engineering firm Eole Water has developed a wind turbine that can produce 1,000 liters of clean drinking water every day by filtering and collecting moisture out of the air. Seeing how the ...

Conventional cooling methods for wind turbine transmissions present notable drawbacks. Direct air cooling ... highlighting the flow of vapor and liquid. To rigorously assess LTS’s performance ...

In 2010, the University of Delaware and Gamesa Technology Corporation (now Siemens Gamesa Renewable Energy) joined forces to install a utility-scale 2-megawatt (2-MW) wind turbine at UD’s Hugh R.
