CFD Provides Insight Into Mystery Fossils

Fossilized imprints of Parvancorina from over 500 million years ago have puzzled paleontologists for decades. What makes it difficult to infer their behavior is that Parvancorina have none of the familiar features we might expect of animals, e.g., limbs, mouth. In an attempt to shed some light on how Parvancorina might have interacted with their environment researchers have enlisted the help of Computational Fluid Dynamics (CFD).

April 2017: Fluidics and Stonehenge Vortex

It's April and therefore it's time to confess that there isn't a solstice day vortex generated at Stonehenge, unless you are in the April Fools' Day distortion field. However, there are fluidic components that mimic digital logic gates.

Fluidic Logic

Fluidic logic (fluidics) uses specially designed fluid paths to perform logic operations, such as AND, OR, and NOT gates. In electronics logical operations underpin all the digital devices that depend on CPUs for their brains. Using Computational Fluid Dynamics (CFD) we can quickly explore potential fluidic components.

March 2017: CFD and Aerodynamics

The two themes for this month's newsletter are Computational Fluid Dynamics (CFD) and aerodynamics. First check out our revamped CFD description now with a what, why, and how treatment. Next see how aerodynamics can help you go dangerously fast downhill. Then finally, discover the aero effects of fenders (mud guards) on your bicycle wheels.

Bicycle Wheel and Fender Aerodynamics

In the bicycle world aerodynamics has taken on an ever increasingly important role. Cyclists are willing to go to great lengths and expense to realize performance enhancements through optimized aerodynamics in bicycle frames, wheels, and components. I thought it would be interesting to see where in the spectrum of aerodynamics performance disc rotors and fenders (mud guards) lie using Computational Fluid Dynamics (CFD) as our guide.

What is Computational Fluid Dynamics?

Computational Fluid Dynamics, also known as CFD, is the digital equivalent of a real world wind tunnel or flow bench. With CFD you can simulate the air flow around a racing car, the water flow through a heating system, and a whole host of other applications wherever a gas and/or liquid (including multiphase) flows. From your CFD simulation you can determine flow quantities, e.g., lift, drag, pressure loss, velocity profiles, and pressure distributions, to help guide your design.
