The motion of a gas bubble rising due to gravity in a liquid has been studied from many centuries ago and continues to be a problem of great interest today. Interestingly, the fact that this dynamics ...

These strangely-shaped twisted-toroid propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, ...

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 ...

This paper by TSAW Drones discusses the need for less noise in UAVs, how these toroidals can benefit the drone industry, how these propellers came to be and how exactly they reduce the noise. Also, in ...

Surface wrinkling morphologies in various living matter with toroidal geometry. (a) Bidirectional stripes on a garlic. (b) Hexagonal-labyrinth bistable patterns on a dehydrated pepper. (c) Transverse ...

Researchers introduces the first toroidal, light-driven micro-robot that can move autonomously in viscous liquids, such as mucus. This innovation marks a major step forward in developing micro-robots ...

As industries across the board strive for greater efficiency and cost savings, a new technology has emerged as a potential solution: the toroidal propeller. This innovative propeller design, inspired ...
