Measuring Oscillatory Velocity Fields Due to Swimming Algae
Jeffrey S. Guasto, Karl A. Johnson, J. P. Gollub
In this fluid dynamics video, we present the first time-resolved measurements of the oscillatory velocity field induced by swimming unicellular microorganisms. Confinement of the g…
Oscillatory Flows Induced by Microorganisms Swimming in Two-dimensions
Jeffrey S. Guasto, Karl A. Johnson, J. P. Gollub
We present the first time-resolved measurements of the oscillatory velocity field induced by swimming unicellular microorganisms. Confinement of the green alga C. reinhardtii in st…
Hydrodynamic Irreversibility in Particle Suspensions with Non-Uniform Strain
Jeffrey S. Guasto, Andrew S. Ross, J. P. Gollub
A dynamical phase transition from reversible to irreversible behavior occurs when particle suspensions are subjected to uniform oscillatory shear, even in the Stokes flow limit. We…
Mixing by Swimming Algae
Jeffrey S. Guasto, Kyriacos C. Leptos, J. P. Gollub +2
In this fluid dynamics video, we demonstrate the microscale mixing enhancement of passive tracer particles in suspensions of swimming microalgae, Chlamydomonas reinhardtii. These b…
Predicting the progress of diffusively limited chemical reactions in the presence of chaotic advection
P. E. Arratia, J. P. Gollub
The effects of chaotic advection and diffusion on fast chemical reactions in two-dimensional fluid flows are investigated using experimentally measured stretching fields and fluore…
Curvature Fields, Topology, and the Dynamics of Spatiotemporal Chaos
Nicholas T. Ouellette, J. P. Gollub
The curvature field is measured from tracer particle trajectories in a two-dimensional fluid flow that exhibits spatiotemporal chaos, and is used to extract the hyperbolic and elli…
