If you are into fluid dynamics then you have a real treat in store over the next couple of days. The American Physical Society's (APS) Division of Fluid Dynamics (DFD) meeting is underway in San Diego and runs November 19-20, 2012. For a taster of the eagerly anticipated presentations here's a brief selection ranging from huddling penguins to knuckleball soccer kicks.

SC12 - the meet-up for all things supercomputing is now over. Our Microsoft collaborator, Wen-ming Ye, was at SC12, and while he was on the show floor he snapped some pictures of the Asetek liquid-cooling cluster running Caedium CFD simulations. So for anyone who missed the show, enjoy the pictures below thanks to Wen-ming.

Another news blast, this time with an aerodynamics theme. Read on to discover how trucks can be more efficient, how racecars and bikes can go faster, and how to make a stunning McLaren ad. Hint - it's all down to aerodynamics.

More F1 in Schools news - Rapid Motion, a joint team from Australia and Germany, finished 4th overall at the 2012 F1 in Schools World Finals held in Abu Dhabi. Using Caedium Professional CFD simulations the team analyzed the aerodynamics of various designs resulting in a 16% improvement in average speed over their baseline car.
Congratulations go out to F1 in Schools team Revved Up who have qualified for the Australian F1 in Schools National Finals, after a convincing win at their state competition. Revved Up used Caedium Professional CFD simulations to help optimize the aerodynamics of their car and to good effect by all accounts!

It seems that analogies between fluid flow and other physical processes continue to proliferate. Add to that list the analogy between a hydraulic jump (think smooth-shallow to rough-deep transition in a sink under a running tap) to a white hole (think black hole running backwards in time). Physicists at the University of Nice Sophia Antipolis, France recently showed through "...an experimental demonstration that the circular hydraulic jump represents a hydrodynamic white hole...".

Browsing through the news today I can across an interesting array of fluid dynamics related stories that I thought I'd share. So if you want to see how the Williams F1 team uses CFD and wind tunnels, or why a half-full (or is it half-empty?) bottle of water breaks when you hit it in a certain way (clue: cavitation), or how to make nanoballs (clue: bristles), and more, check out the links below.

I think everyone is well aware of the link between tsunamis and earthquakes after the devastation wreaked in recent years on Japan and Indonesia. However, there is a lesser known water wave called a seiche that is limited to semi-enclosed and fully-enclosed bodies of water, such as lakes, bays, swimming pools, and even puddles. I went searching for links between earthquakes and fluid dynamics after I experienced a minor earthquake (4.0 magnitude) here in New England.

What if you could change the shape of a tensile structure according to the natural loads, such as wind forces, it experiences? In exploring this question researchers at the University of Stuttgart and the company Bosch Rexroth came up with a tensile canopy (membrane) - nothing new there. However, their novel design uses a feedback system driven by a sensor array connected to hydraulic rams that apply counter forces to natural loads.
