Understanding dynamic stall at high speeds

Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by aircraft. Read Full Article Here…

How plants can generate electricity to power LED light bulbs

Researchers have discovered that living plants are literally ‘green’ power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an ‘hybrid tree’ made of natural and artificial leaves can act as an innovative ‘green’ electrical generator converting wind into electricity….

Making wind farms more efficient

With energy demands rising, researchers have completed an algorithm — or approach — to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their customers. Read Full Article Here For more great articles: Wind Energy News

Magnetic pumping pushes plasma particles to high energies

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have…

Windier wind farms

Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind returns. Read Full Article Here…

Physicists train robotic gliders to soar like birds

Scientists know that upward currents of warm air assist birds in flight. To understand how birds find and navigate these thermal plumes, researchers used reinforcement learning to train gliders to autonomously navigate atmospheric thermals. The research highlights the role of vertical wind accelerations and roll-wise torques as viable biological cues for soaring birds. The findings…
