Bio-inspired one-way-flow pipes handle liquid like sharks digest food

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type of potentially more robust one-way-flow pipe, which … Continue reading Bio-inspired one-way-flow pipes handle liquid like sharks digest food

Harvard’s bizarre “metafluid” packs programmable properties

Harvard engineers have created a strange new “metafluid” – a liquid that can be programmed to change properties, like its compressibility, transparency, viscosity and even whether it’s Newtonian or not.Continue ReadingCategory: Materials, ScienceTags: … Continue reading Harvard’s bizarre “metafluid” packs programmable properties

In fluid dynamics, hard science often comes with dazzling aesthetic beauty – a fact the American Physical Society highlights annually with a photo/video contest. Here are this year’s winners – equal parts fascinating, hypnotic and visually stunning.Con… Continue reading Gallery of Fluid Motion: Science at its most visually stunning

Variable-Nozzle Ducted Fan Provides Fluid Dynamics Lessons

Any student new to the principles of fluid dynamics will be familiar with Bernoulli’s principle and the Venturi effect, where the speed of a liquid or gas increases when the …read more Continue reading Variable-Nozzle Ducted Fan Provides Fluid Dynamics Lessons

Bug hacks physics with “butt flickers” to launch pee at 40 G’s

We’re willing to bet you’ve never given much thought to how bugs urinate, but even if you did you probably wouldn’t imagine them using butt-based pinball paddles to flick drops of pee at 40 G’s, using physics never before seen in nature.Continue Readin… Continue reading Bug hacks physics with “butt flickers” to launch pee at 40 G’s

Electron whirlpools: Scientists witness electricity behaving like water

Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics.Continue ReadingCategory: Physics, ScienceTags: Electron Microscop… Continue reading Electron whirlpools: Scientists witness electricity behaving like water

Desktop Wind Tunnel Brings Aerospace Engineering to the Home Gamer

Computer simulation is indispensable in validating design and used in every aspect of engineering from finite element analysis to traffic simulation to fluid dynamics. Simulations do an amazing job and at a fraction of the time and expense of building and testing a scale model. But those visceral ah-ha moments, …read more
