Perfect Gifts for CFDers

Having previously determined how Santa makes his deliveries using a Reality Distortion Field, now we have also figured out how he selects the perfect gifts for each and every CFDer.

Intuition and Fluid Dynamics

Some fluid dynamics is intuitive, e.g., the water flow along a pipe, where what goes in one end comes out the other. However, most applications no matter how simple are anything but intuitive, e.g., the drag of a ball moving through air.

Turbulence Model Selection

Most Computational Fluid Dynamics (CFD) software provides an array of turbulence models. Knowing which model to select is not always an easy decision given trade offs between accuracy and computing requirements.

Double Diffusers and F-Ducts Explained

If you followed Formula 1 in 2009 and 2010 you will probably recall the terms double diffuser and F-duct. However, unless you were in the aerodynamics department of an F1 team during that period you will probably only have a sketchy idea of how these devices actually produced the elusive, race-winning, downforce that is key to F1 success.

Fluid Dynamics News: Hydraulic Capsule Pipelines and Fish Farming Sea Cages

Time for some fluid dynamics news with a Computational Fluid Dynamics (CFD) slant. Check out how CFD was used to make hydraulic capsule pipeline predictions and simulate the flow through fish farming sea cages.

Symmetry for CFD to the Rescue

Symmetry is a simple but powerful concept that you can use to speed up your Computational Fluid Dynamics (CFD) simulations and reduce your memory requirements. Join me in an exploration of a simple symmetry case.
