Weak and Strong Form CFD

If you are given production-ready detailed CAD geometry (nuts, bolts, and all) for Computational Fluid Dynamics (CFD) analysis you have to ask yourself, is this really an engineering endeavor or a marketing exercise? Given the effort to produce a complete, detailed CAD model, it is unlikely that any significant changes will be looked upon favorably. Instead you will likely find that CFD is to be used in its weakest form, i.e., Colorful Fluid Dynamics (CFD) for marketing.

CFD Helps Unconventional Concept Designs Succeed

When you find yourself tasked with the design of something unconventional, then Computational Fluid Dynamics (CFD) is here to help. For instance consider the aircraft industry. It used to be that the dominant type of aircraft required a pilot and therefore a cockpit with a good view of the world. Then Unmanned Aerial Vehicles (UAVs) went mainstream and everything changed.

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!

CFD For A Complete Dust Collector

Having performed Computational Fluid Dynamics (CFD) simulations for each component of Matthias Wandel's "Small Dust Collector," the time has come to assemble and test the entire system - virtually, of course. Recall that the main components of the dust collector are a cyclone, a filter assembly, and a blower.

Remote CFD is Easy

You know how it is - you are away from the office and you are desperate to check in on a series of Computational Fluid Dynamics (CFD) simulations you are running back at your base. Then once the simulations finish you'd like to take a moment to look at each one with all the benefits of hardware accelerated graphics on your laptop, while still enjoying your latte at Starbucks. Well you can do both today without any extra outlay using Caedium and free apps from Google - let me describe how.

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.

CFD Simulation of Airflow Through Filters in a Dust Collector

After using Computational Fluid Dynamics (CFD) to simulate the blower and cyclone in Matthias Wandel's "Small Dust Collector" we next turn our attention to the last remaining major component - the twin filter assembly. The filters remove fine particles that escape the cyclone, leaving the air to pass through the blower and exit to the atmosphere.

CFD Analysis of a Homemade Cyclone

Hot on the heels of my recent Computational Fluid Dynamics (CFD) analysis of the blower for Matthias Wandel's "Small Dust Collector" comes a new CFD study of his cyclone. Cyclones are used in many industries to separate fluids from particles. In Matthias' case he wanted to separate sawdust and wood shavings from air collected from the working area of various woodworking machines.

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.
