Go Full Circle With CFD

There is a certain circular symmetry to the process by which you can perform Computational Fluid Dynamics (CFD) simulations on a computer, which is also due in part to CFD.

CFD Expertise Is Your Modern Day Pick and Shovel

News just in from Bloomberg is that Larry Page, of Google fame, is funding not one (Zee.Aero) but two (Kitty Hawk) personalized flying-machine (dare I say flying cars?) startups. With a number of other companies pursuing the same goal, it seems a gold rush of sorts is on. Yet remember the real gold rush? The real benefactors were the pick and shovel makers. The equivalent in this flight to the future are employees with highly prized skills brought to bear on a decidedly tricky problem. And at the sharp end of those with specialized skills are...Computational Fluid Dynamics (CFD) experts - providing valuable insights into aerodynamics, propulsion, batteries, and electrical/electronics cooling.

CFD Benefits From 3D Printing

It turns out that preparing geometry models for 3D printing has a lot of similarities with preparing geometry for Computational Fluid Dynamics (CFD). Both require watertight non-manifold geometry, otherwise your model will plunge your 3D printer or your CFD software into chaos.

Cutting Planes Reveal Yet More Hidden CFD Secrets

Yet another way to reveal the hidden secrets of your Computational Fluid Dynamics (CFD) simulation is to create a face, usually a plane and often referred to as a cutting plane, to serve as a target for interpolated results.

No Colorful Fluid Dynamic Paint Yet

I'm sure you realized that the post on Colorful Fluid Dynamic Paint published on April Fools' Day was more than a coincidence. Full confession - Colorful Fluid Dynamic Paint is fake. However, if we ever do get something like it, I'll be first in line to try it!

Colorful Fluid Dynamic Paint

Forget having a single paint color for your next vehicle purchase and instead go with Colorful Fluid Dynamic paint that changes color according to the airflow around your vehicle. Once only the domain of wind tunnels, pressure sensitive paint and the newly available air speed paint can produce stunning dynamic surface contours as you drive.
