Particle image velocimetry (PIV) has become the chief experimental technique for velocity
field measurements in fluid flows. The technique yields quantitative visualizations of the …

Compared with traditional underwater vehicles, bio-inspired fish robots have the advantages
of high efficiency, high maneuverability, low noise, and minor fluid disturbance. Therefore …

Theory and modelling remain central to improving our understanding of undulatory and
oscillatory swimming. Simple models based on added mass can help to give great insight …

The propulsive performance of an unsteady heaving and pitching foil is considered, and an
extensive experimental parameter space of motion amplitudes, frequencies, and phase …

Some fishes and sea turtles are distinct from ectotherms by having elevated core body
temperatures and metabolic rates. Quantifying the energetics and activity of the regionally …

Experiments are reported on the performance of a pitching and heaving two-dimensional foil
in a water channel in either continuous or intermittent motion. We find that the thrust and …

The present study examines the energy efficiency of self-propelled hydrofoils for various
modes and kinematics of swimming adopted by various body-caudal fin fish. In particular …

The structure of swimmers' wakes is often assumed to be an indicator of swimming
performance, that is, how momentum is produced and energy is consumed. Here, we …

We provide a critique of mathematical biology in light of rapid developments in modern
machine learning. We argue that out of the three modelling activities—(1) formulating …

Intermittent swimming and schooling individually offer the possibility of energy economy for
fish. To study the role of the simultaneous use of both behaviors, the intermittent swimming …
