Pumping and Steady Streaming driven by Two-Frequency Oscillations of a Cylinder
Hyun S. Lee, William D. Ristenpart, Robert D. Guy
The classical problem of steady streaming induced by an oscillating object has been studied extensively, but prior work has focused almost exclusively on single-frequency oscillati…

Optimizing Metachronal Paddling with Reinforcement Learning at Low Reynolds Number
Alana A. Bailey, Robert D. Guy
Metachronal paddling is a swimming strategy in which an organism oscillates sets of adjacent limbs with a constant phase lag, propagating a metachronal wave through its limbs and p…

Quantification of Flagellar Gait Changes with Combined Shape Mode Analysis and Swimming Simulations
Kelli E. Gutierrez, Becca Thomases, Paulo E. Arratia +1
Many different microswimmers propel themselves using flagella that beat periodically. The shape of the flagellar beat and swimming speed have been observed to change with fluid rhe…
