Is it possible to create a vehicle that uses the wind to move itself directly downwind faster than the wind does? Strangely enough, it is. The concept has been the Keep reading
Non-Newtonian fluids are a favorite for displaying odd behaviors. High-speed video simply improves the experience. Remember, though, that non-Newtonian fluids don’t actually become solids when you hit them. They just Keep reading
Boiling a liquid is a common enough phenomenon that we are all familiar with it. But, as with many aspects of fluid mechanics, removing gravity drastically changes the situation.
Bubbles are all about surface tension and minimizing energy. Arrange things just right and you can even make square ones. (via JetForMe)
Wired Science and 80 beats on Discover have a few more summaries on the recent flying fish paper and its findings.
New research using wind tunnel measurements of (dead) flying fish is giving new insight into how these fish are able to fly over the waves. Lift and drag data indicates Keep reading
The von Karman vortex street isn’t just found in the wake of cylinders in a lab. Wind moving over islands frequently creates the effect, as in this MODIS Aqua image Keep reading
One of the topics in fluid dynamics almost everyone has come across is the explanation of how airplanes produce lift. Using Bernoulli’s principle–which relates velocity and pressure–and a picture of Keep reading
As those of us in Texas get drenched by Tropical Storm Hermine, it’s worth taking a moment to enjoy the beauty of each rain drop hitting a puddle.
Cooling helium down to 2 Kelvin creates a superfluid, a special type of fluid that exhibits some bizarre properties. Superfluids have zero viscosity, meaning that they are frictionless, and infinite Keep reading
