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.

CFD Analysis of a Blower for a Small Dust Collector

I recently came across an interesting fluid dynamics project modestly titled "Small Dust Collector" by Matthias Wandel of Woodgears. The unusual twist - at least from my metal-orientated view of the world - was the use of wood as the primary construction material. The project includes the construction of a blower, cyclone, filter housing, and filter manifold - all prime candidates for Computational Fluid Dynamics (CFD) simulations. I sense a series of blog posts, so first let's take a look at the blower also known as a centrifugal fan or squirrel cage fan.

Fluid Device Design is Like Herding Cats So Let CFD Help

Where the action of a fluid is the primary concern in the design of a device, e.g., a cyclone, sometimes it can seem that fluid is going out of its way to be difficult - a lot like trying to herd cats. Fluid device designers have to carefully match geometry to flow rates to meet performance criteria. However, if they were to rely solely on physical testing, then their task is that much harder and more costly because they can't easily visualize the flow behavior. Let Computational Fluid Dynamics (CFD) save you money and time as a supplement to physical testing.

Reduced Complexity 3D Models for CFD

Reduced complexity 3D model for Computational Fluid Dynamics (CFD) is a great way to avoid getting bogged down in details that are not relevant for a simulation. 3D video games and 3D animation applications have been using reduced complexity 3D models combined with texture maps to present rich visuals since the dawn of the digital age. These models and the concepts to build them can be extremely useful for CFD.
