Esperanto For Computational Fluid Dynamics

Big news from Europe - a new European directive has just been passed that requires all software applications released in the European Union to support the Esperanto language by June 2012. This is part of a larger European directive mandating that all European countries are to adopt Esperanto as the Europe-wide common language by 2014.

How to Lose F1 Races with a Wind Tunnel and CFD

I recently came across a blog post "How to lose races with CFD" [source: Another Fine Mesh] related to the CFD-only strategy pursued by the Marussia Formula 1 Team (formerly Virgin Racing) during the 2010 and 2011 F1 seasons. It seems such an easy conclusion to make, right? During its first 2 F1 seasons the Marussia team garnered a lot of publicity thanks to their CFD-only (no wind tunnel testing) strategy and during that period they didn't win a race, therefore CFD must lose races, right? Not so fast.

Flying Humans Spotted Over New York

Yes you read that right - three humans were recently spotted flying over New York without a jetpack in sight. Don't believe me? Then watch this video:

Puddle: Another Fluid Game

Do you sometimes feel like your Computational Fluid Dynamics (CFD) simulation just needs a little nudge to do the right thing? Well I'm sure you'll appreciate (need even!) some light relief with the fluid-based video game Puddle. Puddle is all about nudging and manipulating the world so your precious fluid gets to its destination through a fiendish puzzle-like maze.

Fluid Wrist Watch for a Fluid Dynamicist

Any fluid dynamicists out there searching for just the right wrist watch? Well the search is over, check out the HYT H1 [source: Gizmodo] fluid-themed watch from "The Hydro Mechanical Horologists" - try saying that after too much fluid!

An Update on HPC's Missing Middle

The report "Council on Competitiveness and USC-ISI Broad Study of Desktop Technical Computing End Users and HPC" [pdf] by the Council on Competitiveness and sponsored by DARPA in 2008 found that a large number of companies deployed virtual prototyping and data modeling software (e.g., Computational Fluid Dynamics [CFD]) on entry level High Performance Computing (HPC) or desktop computers as opposed to realizing the performance and fidelity gains available with true HPC systems. In a subsequent follow up report [pdf] the authors coined the phrase 'the missing middle' to describe the gap in HPC usage.

RC Car Integrates Advanced Aerodynamics Package

Going fast and aerodynamics are intimately related, whether it's for a Formula 1 car or in this case for a remote control (RC) car. The Traxxas XO-1 is billed as "The World's Fastest Ready-To-Race Supercar" with a 0-100 mph time of under 5 seconds. More interesting than its out-and-out straight-line speed is that this RC car employs advanced aerodynamics for generating downforce.

CFD Study Confirms Fabric Ducts Are More Efficient Than Metal Ducts

An extensive Computational Fluid Dynamics (CFD) study [pdf] performed over 10 months by a team at Iowa State University [source: green building pro] confirmed what many room occupants long suspected - that fabric ducts offer better indoor air comfort compared to traditional metal ducts. Equally impressive, the study found that the fabric ducts provided a 22-27% improvement in energy efficiency compared to equivalent metal ducts.

3D Printing Revolution Underway

With the ever expanding and affordable array of 3D printers (also known as rapid prototyping machines) new opportunities abound. I first covered 3D printing back in 2007. Since that time The New York Times has run a number of articles on 3D printing (Don't believe me? Then try searching Google for 3d printing - an indication if ever it were needed that 3D printing has gone mainstream and entered the public's consciousness. So enough with all this virtual engineering, at some point you have to get physical and the 3D printing revolution is a great place to start.

Yet Another Roadable Aircraft

Yet another roadable aircraft or flying car? Yes, but the Model 367 BiPod [source: gizmag] is different because of who designed and built it. Burt Rutan - of SpaceShipOne fame - retired earlier this year from legendary prototype aircraft maker Scaled Composites. His last project was a hybrid-powered road and air vehicle. The twin fuselage, a signature design feature of many Scaled Composites airplanes, makes for a uniquely odd looking car design. One cockpit controls the vehicle while on the ground and the other cockpit controls the vehicle while in flight.
