Wave-averaged motion of small particles in surface gravity waves: effect of particle shape on orientation, drift, and dispersion
Nimish Pujara, Jean-Luc Thiffeault
Particles such as microplastics and phytoplankton suspended in the water column in the natural environment are often subject to the action of surface gravity waves. By modelling su…
Microswimmer trapping in surface waves with shear
Francesco Michele Ventrella, Nimish Pujara, Guido Boffetta +3
Many species of phytoplankton migrate vertically near the surface of the ocean, either in search of light or nutrients. These motile organisms are affected by ocean waves at the su…
The mathematics of burger flipping
Jean-Luc Thiffeault
What is the most effective way to grill food? Timing is everything, since only one surface is exposed to heat at a given time. Should we flip only once, or many times? We present a…
Open-flow mixing and transfer operators
Anna Klünker, Kathrin Padberg-Gehle, Jean-Luc Thiffeault
We study finite-time mixing in time-periodic open flow systems. We describe the transport of densities in terms of a transfer operator, which is represented by the transition matri…
Nonuniform mixing
Jean-Luc Thiffeault
Fluid mixing usually involves the interplay between advection and diffusion, which together cause any initial distribution of passive scalar to homogenize and ultimately reach a un…
Reaching for the surface: Spheroidal microswimmers in surface gravity waves
Kunlin Ma, Nimish Pujara, Jean-Luc Thiffeault
Microswimmers (planktonic microorganisms or artificial active particles) immersed in a fluid interact with the ambient flow, altering their trajectories. In surface gravity waves,…
