Fluids and Flows
Date:
Saturday, February 18, 2017 - 10:30
Venue:
Martin Wood Lecture Theatre, Clarendon Laboratory
The flow of liquids and gases is described by the Navier-Stokes equation
Overview:
ρ { + ( u ⋅ ∇ ) u } = −∇ p + η ∇ 2 u
This simple equation can describe how fluids move across a huge range of length scales, from ocean currents to swimming algae; from the drag behind racing cars to the raindrops on a spider's web. Join us to explore the wonderful world of fluids and flows.
Centimetres: Fluids all around us
Video Podcast | Presentation (PDF)
Julia Yeomans will talk about fluids and flows all around us: from superhydrophobic surfaces and how animals and plants keep dry, to bouncing droplets and balloons.
Microns: The bacterial viewpoint
Video Podcast | Presentation (PDF)
Ramin Golestanian will introduce you to Life at Low Reynolds number and ask how microorganisms can swim, navigate, and coordinate their activities. You will discover how the left-right symmetry is first broken in a developing embryo, and investigate the medically important question of how mucus is shifted in our lungs and what happens when things go wrong.
Kilometres: Turbulence
Video Podcast | Presentation (PDF)
Fasten Your Seat Belts: Turbulent Flows in Nature. Turbulence is ubiquitous in nature, and it often causes us headaches both literal and metaphorical. From unpredictable weather to the mixing of milk in our coffee, Michael Barnes will talk about how turbulence arises and our ongoing struggle to control it.Ta
