To make fluid flow in one direction down a pipe, it helps to be a shark. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2024 / 09 / 240925122917.htm ...

They fabricated structures inspired by Tesla valves, originally designed by Nikola Tesla in the 1920s. Tesla's "valvular conduit" can force fluids to flow more quickly in one direction than ...

However, on a shoot whose fins -- although still pointing at the tip -- have a more upward profile, the direction of movement is instead to the root. The flow direction depends on the angles ...

Their prototypes kept fluids flowing in one preferred direction with no need for flaps to control that flow and performed significantly better than so-called "Tesla valves," particularly when made ...

Flaps perform essential jobs. From pumping hearts to revving engines, flaps help fluid flow in one direction. Without them, keeping liquids going in the right direction is challenging to do.
