Fishes have learned how to achieve outstanding swimming performance through the
evolution of hundreds of millions of years, which can provide bio-inspiration for robotic fish …

Schooling in fish is linked to a number of factors such as increased foraging success,
predator avoidance, and social interactions. In addition, a prevailing hypothesis is that …

Numerical studies are presented on the propulsive performance and vortex dynamics of
multiple hydrofoils pitching in an in-line configuration. The study is motivated by the quest to …

Locomotion of aquatic animals involves flapping of their body to generate lift and thrust.
Through evolution, they have mastered their ability to move through complex environments …

Locomotion is the act and process of moving from place to place, which is fundamental to
the life history of all mobile organisms. While the field of biomechanics encompasses the …

Anguilliform and carangiform fish have a thinner and thicker body along with a smaller and
larger undulating wavelength-based kinematics for their propulsion, respectively. The …

New experiments examine the interactions between a pair of three-dimensional (AR= 2) non-
uniformly flexible pitching hydrofoils through force and efficiency measurements. It is …

This paper explores the use of hydrodynamic eigenmode decomposition as a means of
generating optimal swimming kinematics of slender three-dimensional bodies. The …

Simulations are reported on the behavior of two tandem symmetric foils in an in-line
configuration undergoing pitching motion. The Reynolds number was varied between 1000 …

The effects of two different pitching frequencies (that is, Strouhal number, St) on the wake
structure generated by two foils of aspect ratio 1.0 are examined numerically at a Reynolds …
