Helical Strakes with your Chimney?

Helical strakes are often used on chimneys to reduce vortex induced vibration (VIV). However, these strakes also have a significant drawback - they induce massive increases in drag and side forces that have significant structural implications for the chimney. Read on for a Computational Fluid Dynamics (CFD) study that compares a smooth cylindrical chimney to the same chimney with helical strakes.

Turning Vanes Required

Do you want turning vanes with your duct work? Yes, if you are considering a square corner and you want to minimize your fan power requirement. Don't take my word for it, instead consider this Computational Fluid Dynamics (CFD) study that compares a vaneless square corner with both small turning vanes and large turning vanes.

Elephants and Computational Fluid Dynamics

Zoology professor Warren Porter leads a team of researchers from the University of Wisconsin-Madison that uses Computational Fluid Dynamics (CFD) to simulate heat transfer and drag. No big deal you say, until you hear that the subject of his CFD simulations is an elephant!

Questionable Approach Reverse

After a thorough design review I decided to reverse the Questionable Approach applied to the Caedium interface described in "Counterintuitive Usability With The Questionable Approach". I think the April Fools' Day reality distortion field got the better of me. Rest assured that the next release of Caedium will have a new set of gorgeous different icons to compliment the new ribbon-like interface.

Counterintuitive Usability With The Questionable Approach

Researchers at the Media Attention Deficit (MAD) Lab recently reported findings that run counter to accepted norms in software usability design. The MAD Lab researchers found that the more difficult software was to use, the more memorable the software became. In light of this research we have replaced all the icons in Caedium with the same question mark icon in an effort to make our software more difficult to use, but easier to remember.

In the F1 World - Aerodynamics is Everything

The BBC has run a four-part series on "How to make an F1 car" based on an interview with former Formula 1 car designer Gary Anderson. The series provides a great insight into the F1 design process and highlights the overriding importance of aerodynamics. Follow the links to read the full articles.
