April 2015: CFD for a Fully Assembled Dust Buster

Have you ever wondered what a complete Computational Fluid Dynamics (CFD) simulation of a dust collector will reveal? Well wonder no more! Last month you saw the CFD analysis for each component of a dust collector and this month you can see the CFD analysis of a fully assembled dust buster. Of course while you are running your own dust buster CFD simulation you'll want to check in on its progress wherever your schedule takes you, so be sure to read the article on remote CFD. Then, round out your fluids-themed day with some light relief - did you know that we renamed the Navier-Stokes equations for April Fools'? You do now!

March 2015: CFD Dust Busting

This is Computational Fluid Dynamics (CFD) dust busting month! I've performed a series of CFD simulations on the major components of a "Small Dust Collector" by Matthias Wandel of Woodgears. This month's articles systematically evaluate the performance of the blower (reappearing from last month for completeness), cyclone, and filter assembly, so you too can apply the same technique to match your own pumps/blowers to pressure drops through your system.

February 2015: CFD in Words Backed Up With Action

Words then action in perfect unison this month. First the words - discover how reduced complexity models combined with Computational Fluid Dynamics (CFD) can help you rapidly gain insights into your design. Then the action - see how a reduced complexity model combined with automated CFD simulations can rapidly produce a fan curve and efficiency profile of a real-world blower for a dust collector with a twist.

January 2015: CFD Review of 2014

Let's draw a line under 2014 with a couple of review articles, so we can clear the decks - refreshed and firing on all cylinders for Computational Fluid Dynamics (CFD) in 2015.

December 2014: Holiday CFD Doodles

The festive holiday season is once again upon us. What better way to mark the occasion than with a Computational Fluid Dynamics (CFD) doodle. No ordinary doodle though, a mega snow globe CFD doodle. Many a doodle has preceded a great innovation, so get your CFD doodle on and share your Caedium CFD doodles with us. Not sure if CFD doodling is for you? Then check out my latest blog posts that include the top 5 reasons to try CFD and why not all CFD GUIs are equivalent. Finally, I'd like to wish you a Merry Holiday and a prosperous New Year.

November 2014: What can CFD do for you?

What has Computational Fluid Dynamics (CFD) done for you lately? Or more to the point - what can CFD do for you? For a brief reminder of the broad range of internal and external CFD flow applications, and for a specific external aerodynamics case study, read on.

October 2014: The Founding Fathers of CFD

The theory on which Computational Fluid Dynamics (CFD) depends was laid way back in the 19th Century, before the dawn of practical computers. Take a moment to marvel at some of the science pioneers armed only with pens and paper who enabled CFD to become an essential engineering tool used today by a wide swath of industries.

September 2014: Geometry Techniques for CFD

The overwhelming majority of issues that prevent a smooth Computational Fluid Dynamics (CFD) process are related to geometry. If geometry issues cause you headaches, then read on for a series of articles that describe techniques to help you navigate around common problems. Once you are done, unwind with a look at how nature uses similar visualizations to those found in CFD.
