A fluidic oscillator is a device with no moving parts that sprays a fluid from side to side. The animations above illustrate how they work. A nozzle funnels a fluid jet through a chamber with two feedback channels. When the jet sweeps close to one side of the chamber, part of the fluid is directed along the feedback channel and back toward the inlet. That flow feeds into a recirculating separation bubble in the middle of the chamber. As that bubble grows, it pushes the jet back toward the other feedback channel, continuing the cycle. Many automobiles use fluidic oscillators in their windshield washer sprays. Check out the award-winning full video from the Gallery of Fluid Motion. (Image credit: M. Sieber et al., source)
Designed by SottoStudios in collaboration with Embraer Executive Jets, Skyacht One is probably the most luxurious private jet in the world.
Inspired by a 1939 custom yacht, the exclusive aircraft combines state-of-the-art technology with the hand-made luxury of the past to create what the studio calls “a yacht that can fly”.
Trimmed in mahogany, the navigation-themed interiors comprise 5 sumptuous cabin zones, including an extravagant master suite with walk-in shower, a conference room, and a dining area. Fitted with adjustable lighting, the generous main cabin features a Chesterfield sofa and a cocktail bar.
Lasers are a great way to deliver a lot of energy very quickly. In this animation, you see a jet of water get struck by a pulse from a powerful X-ray laser. The energy from that laser pulse gets absorbed by the water in a matter of picoseconds - that’s trillionths of a second. All that energy in so little time makes the water vaporizeexplosively. It’s this vapor explosion that breaks the jet in two. As the vapor expands outward, it forces water from the jet into a thin film that forms a cone. The conical film bends back on itself until it strikes the jet and coalesces. For more, check out this video of a similar experiment that looked at laser impacts on droplets. (Image credit: C.
