Welcome to FLOW!

Flow is an ongoing Fluid Mechanics series where we explore the concepts of Fluid Mechanics with the aid of a slow motion camera as and when required. The following is a trailer to the series:

  1. Buoyancy
    1. Origins of the Buoyant force
    2. How do hot air balloons work?
    3. Note on average density and how do ships not sink ?
  2. Flow Instabilities
    1. Plateau- Rayleigh Instability
  3. Pilot Wave Hydrodynamics (completed with Nicole Sharp, FYFD)
    1. Introduction
    2. Chladni patterns
    3. Faraday instability
    4. Walking droplets
    5. Droplet lattices
    6. Quantum double-slit experiments
    7. Hydro single- and double-slit experiments
    8. Quantum tunneling
    9. Hydrodynamic tunneling
    10. De Broglie’s pilot-wave theor
    11. Resources and references on pilot wave hydrodynamics
  4. DIY Pilot wave hydrodynamics

Gallery of Fluids

I grew up with this beautiful book titled – “An album of fluid motion” which was put together by Milton Van Dyke from Stanford. It was an extraordinary display of fluid action caught on camera.

When I was pursuing the Flow Series and experimenting with a lot of fluid setups, I captured a few interesting photographs and began to compile them together. If you would like to know more about these images, send me and email at 153armstrong@gmail.com and I can help you set it up. Cheers!
