“Big whorls have little whorls that feed on their velocity, and little whorls have lesser whorls and so on to viscosity” – Lewis Fry Richardson Introduction Although this post shall take great advantage of the notion of vorticity to get a glimpse on the small scale organized fluid elements of significant life-time and scale we call …
Motivation: There are various type of instabilities for a number of flow patterns. The intention of this post is to investigate how these instabilities may trigger laminar-turbulent transition. I shall do my best to classify these routes leading from a stable laminar to a disturbed one flow, and base my path on the mechanisms responsible …

We've decided to gather for our “All About Cfd” followers our top ten read posts for February. I found the list kinda cool, maybe Some of my own favorites do not appear this month, but nonetheless it’s a wonderful list of posts: All About Turbulence Modeling - The “All You Can Eat” Menu Predictions for CFD …
