First off, I’d like to give a special shout-out to FYFD’s friends at Pointwise, who were kind enough to invite me for a visit this week. For any readers looking for CFD grid-generation software, check them out; they are a fantastic bunch and very good at what they do.
My thanks again to everyone who donated this week to help get me to the APS conference. The campaign is still open if anyone wants to get in on the FYFD wallpapers and stickers on offer to donors. As a reminder, any funds beyond conference costs will go toward improving FYFD, including getting equipment to make FYFD videos. On to the fluids round-up!
- Wired takes us behind the scenes of the creation of Games of Thrones’ dragons. Believe it or not, the VFX team actually did digital simulations of the dragons flying in a wind tunnel.
- Nature dissects whether a submarine at relativistic speeds sinks or floats. (via io9) Note that Nature article says the submarine is in water but the original paper simply says that the submarine is immersed in a fluid and makes no account for the compressibility (or lack thereof) of that fluid.
- Add some excitement to your day with liquid-nitrogen-induced explosions from Distort (via io9).
- Flow Viz shows off a great picture of condensation-induced flow visualization on an airplane wing.
- Check out this awesome video of vibrating lycopodium powder from Susi Sie. (via io9)
- National Geographic considers whether Hawaii’s molasses spill is more or less environmentally damaging than an oil spill.
- Finally, our lead image shows a natural visualization of flow around a kayaker. The foam atop the water forms when air and water mix with the gas produced by decomposing leaves. The photo by Lucas Gilman appeared in Outside Magazine earlier this summer. (via Flow Visualization)
