This Week in CFD

shallow-water-plumeThis week we learned about a new, open-source CFD code called UCNS3D from Cranfield Univ. There’s a survey on engineering computing that I recommend you take. Lots of application stories are linked herein including one about “ambulances for fishermen” which is not a phrase I often hear. Shown here is another application of CFD to simulation of a subsea plume. And you can read a thought-provoking article on an engineering skills gap. Notably, I exhausted all my bookmarked CFD links with this post so let’s hope a lot happens in the next few days or next week’s post will be a bit light.

Crinkle Surface

crinkleWhen you make a cut through a volume mesh and create a crinkle surface it’s because you want to get the precise details of what things look like. On the other hand, when you put a crinkle surface in a concert hall it’s because you want to diffuse a situation called flutter echo.

That’s exactly what Steven Holl Architects did for the Kennedy Center expansion. Because the concert hall had two parallel walls they surfaced them with crinkle concrete, a 3-inch deep random texture to break-up reflections of the performers’ sound. Click through to the article to see a close-up of the crinkles.
