Mathematicians call the shape of a doughnut a 'toroid'. Physicists call a swirling fluid a 'vortex'. A toroidal vortex, then, is a swirling doughnut of fluid. This video from the Sleek Geeks archive ...

As boring as propeller designs may seem to the average person, occasionally there’s a bit of a dust-up in the media about a ‘new’ design that promises at least a few percent improvement in performance ...

The basic configuration of traditional propellers has not fundamentally changed since the first powered flight by the Wright brothers in 1903. However, as engineers learn more about aerodynamics and ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Recently, a major breakthrough in the field of optical toroidal vortices has been achieved and published in ...

Researchers have developed a next-generation X-ray imager to improve temperature diagnostics in inertial confinement fusion experiments at the National Ignition Facility, enhancing spatial resolution ...

Physicists have managed to create an experimental structure with a strong toroidal dipole response of the electromagnetic field over a wide frequency range. This response is associated with a special ...

When comparing the efficiency of different wind turbine blade designs, [AdamEnt] found using a hair dryer wasn’t the best tool for the job. Enter his new 3D-printed wind tunnel. After several ...
