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.

November 2016: Fluid News Roundup

Make way for a general fluid news roundup this month with Formula 1, hydraulic capsule pipelines, and fish farming sea cages. This is probably the first time those three topics have appeared together, so savor the moment as it is unlikely to occur again.

In Search of The Remaining 20 in The Pareto 80-20 Rule

Pareto analysis usually reveals a golden 80-20 rule for squeezing performance out of things. In other words - it means the majority of the performance (80%) is typically governed by a minority (20%) of factors. Pareto analysis applies equally across many disciplines from sports (marginal gains anyone?) to product design.
