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 coordinated motion of animal groups through fluids is thought to reduce the cost of
locomotion to individuals in the group. However, the connection between the spatial patterns …

A scaling formulation is constructed for the hydrodynamic thrust by an undulatory propulsor
based on the vortex dynamics. It states that the propulsion thrust is in scale with the square …

Scaling laws for the thrust production and power consumption of a purely pitching hydrofoil
in ground effect are presented. For the first time, ground-effect scaling laws based on …

Cetaceans convert dorsoventral body oscillations into forward velocity with a complex
interplay between their morphological and kinematic features and the fluid environment …

We report results from an experimental investigation on the fluid-structure interactions of
flap** foils with tapered thickness profiles actuated in a quiescent viscous fluid. We seek …

The variation in thrust generation with respect to Reynolds number was numerically
evaluated for an oscillating foil with combined pitching and heaving motion at a range of …

Several fishes swim by undulating a thin and elongated median fin while the body is mostly
kept straight, allowing them to perform forward and directional maneuvers. We used a …

Animals and bio-inspired robots can swim/fly faster near solid surfaces, with little to no loss
in efficiency. How these benefits change with propulsor aspect ratio is unknown. Here we …

Using fluid–structure interaction computational modelling, the hydrodynamic performance of
bio-inspired elastic propulsors with tapered thickness that oscillate in an incompressible …
