Undergraduate Colloquium

Roughing up wings: Drag, boundary layers, separation and bumps

Undergraduate Colloquium, University College London, March 2015

An aeroplane wing admires the mountains of Greenland

A whistle-stop tour through over a hundred years of fluid dynamics research: we’ll take in the concept of drag, explore boundary layers, admire laminar flow, glimpse turbulence and try to understand separation, all surrounded by the scenery of boundary layer flow control.  Seeing how some very little bumps could save us a lot of money will bring our travels to a close, but hopefully you’ll return having changed your perceptions of an aeroplane’s wings.
