Speaker: Jon Aurnou, UCLA, USA Date/Time: Friday 19th March, 2021. 4:00 pm GMT/11am EST Title: Dynamo Generating Flows in Planetary Cores Abstract: Planetary bodies typically host substantial liquid metal interior fluid layers. The fluid layers are often in turbulent motion due to planetary thermochemical evolutionary processes. This rapidly rotating turbulence can generate coherent, planetary-scale magnetic fields that can protectively shield a...

Speaker: Marina Levy, LOCEAN-IPSL, France Date/Time: Friday 5th March, 2021. 4:00 pm GMT/11am EST Title: Bringing fluid dynamics to life in the ocean Abstract: No flow, no life. Without movement in the fluid, there would barely be any life in the ocean. Fluid movements allow the continuous supply of nutrients essential to photosynthesis in the sunlit layer of the ocean. This...
Speaker: Mattia Gazzola, University of Illinois at Urbana-Champaign, USA Date/Time: Friday 26th February, 2021. 4:00 pm GMT/11am EST Title: Harnessing viscous streaming in complex active systems: mini-bots in fluids. Abstract: Viscous streaming is a phenomenon where an oscillating body generates stable, predictable and robust fluid flows that can be used to manipulate the body’s local surroundings. Viscous streaming has been well...
Speaker: David Quéré, ESPCI-Paris and École Polytechnique, France Date/Time: Friday 19th February, 2021. 4:00 pm GMT/11am EST Title: Acrobatics of non-stick droplets Abstract: Making drops non-wetting increases dramatically their mobility, compared to the situations we are used to. We'll describe a few consequences of this statement, with a particular focus on jumping droplets: two non-stick drops can transfer their surface energy...
Speaker: Cath Noakes, University of Leeds, UK Date/Time: Friday 12th February, 2021. 4:00 pm GMT/11am EST Title: Infection transmission in the built environment – the interface of biology, fluid dynamics, design and human behaviour Abstract: COVID-19 has presented us with the most difficult healthcare and societal challenge we have faced in living memory. To understand the mechanisms of transmission we have...
Speaker: Amin Doostmohammadi, University of Copenhagen, Denmark Date/Time: Friday 5th February, 2021. 4:00 pm GMT/11am EST Title: Engines of life: self-pumping, bio-inspired fluids Abstract: Sperms, bacteria, and tissues, all work as engines of life converting chemical energy into motion. These systems are known as active materials and are capable of self-pumping with prominent role in biological processes, from organ formation to...
Speaker: Isabelle Cantat, Université de Rennes, France Date/Time: Friday 29th January, 2021. 4:00 pm GMT/11am EST Title: Visco-elasticity of Foam Films Abstract: Liquid foam exhibits surprisingly high viscosity, higher than each of its phases. This dissipation enhancement has been rationalized by invoking either a geometrical confinement of the shear in the liquid phase, or the influence of the interface viscosity. However,...
Speaker: Karen Daniels, North Carolina State University, USA Date/Time: Friday 22nd January, 2021. 4:00 pm GMT/11am EST Title: Fingers, fractals, and flow in liquid metals Abstract: A droplet of pure water placed on a clean glass surface will spread axisymmetrically, and a droplet of mercury will bead up into a spherical droplet. In both cases, the droplet is minimizing its surface...
