Space Shuttle Yields One Last Benefit for CFD
The advancements in CFD that have resulted from Space Shuttle applications are too numerous to list. But even in retirement, the shuttles are going to give back to CFD one last time.
Orbiter Autopsies in the May 2012 issue of Smithsonian’s Air & Space magazine quotes NASA deputy principle investigator Charles Campbell describing how 3D scans of the orbiter’s underside will capture the “as-flown” geometry of the vehicle. The as-flown geometry will be simulated at hypersonic conditions and compared to flight data. [The results should be very interesting. I think it was the X-38 that suffered excessive roll when dropped from the wing of a B-52 and the cause of that turned out to be a rather large asymmetry in the as-built versus as-designed geometry.]

CFD for Vehicle Aerodynamics
CFD for Vehicle Aerodynamics, a 3-day workshop to be offered by the University of Chalmers, will share expertise developed at their Vehicle Aerodynamics Laboratory for simulating road vehicles and trains. The differences between LES, DES, and URANS will be discussed as well as mesh generation, numerical schemes, and a practical approach to generating a solution from start to finish. Shape optimization and flow control will be discussed on the course’s second and third days.
The course will be held 29-31 August 2012 in Götenburg.

- Caution: This fluid dynamics blog has a bad word in its name. DO NOT CLICK the link if you are offended by bad language. However, the blog has some interesting articles on fluid dynamics including one illustration of tornadogenesis which is topical considering what happened here in Texas earlier in the week.
- The WorldCAD Access blog asks which of the CAD vendors will be the first to support a gesture-based interface in Windows 8. [I’m interested in knowing whether anyone is interested in using a gesture-based UI for their CAD or CAE software. Are you going to sit for 8 hours a day touching your screen?]

- Intel’s website includes a 12-part series on fluid simulations for video games.
- The Siemens PLM Software blog has started a 3-part series of an FEA analysis in NX. [I know it’s not fluids but it’s nice to see how the other half lives.]

MFD – Martini Fluid Dynamics
Back when I used to enjoy a drink before dinner my preference was a vodka martini, very dry, on the rocks, with a twist. Unlike James Bond, I didn’t specify shaken versus stirred. However, there’s an interesting debate about which mixing technique is better and fluid dynamics can help us settle that issue.
