The following contains what will hopefully become a long list of [ideally] interesting posts pertaining to the experimental measurement and numerical simulation of fluids (gases and liquids), aero- and hydrodynamics and turbulence. I will endeavour to keep theory to a minimum and instead provide a glimpse into various aspects of these flows, visually interesting fluid features, and the numerous approaches that can be used to gain some insight into these chaotic flows.
Turbulence is more than just the phenomena that leaves airline passengers with a queazy feeling in their stomachs. The rapid fluctuations in wind velocity that causes an aircraft to suddenly lift or drop, are a fundamental property of turbulent flows, however such flows are not restricted to the Earth’s atmosphere and actually have a far more significant effect on our everyday lives.
