The fluid dynamics of flapping foils are reviewed in this article. A very wide range of
researches are conducted for the two-dimensional flapping foil which has a relatively simple …

Jellyfish have provided insight into important components of animal propulsion, such as
suction thrust, passive energy recapture, vortex wall effects, and the rotational mechanics of …

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 impact of Strouhal number St (= 0.1–1.0), Reynolds number Re (= 50–2000) and
dimensionless wavelength λ (= 0.5–2.0) on the hydrodynamic performance of a travelling …

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 …

Nearly all fish have flexible bodies that bend as a result of internal muscular forces and
external fluid forces that are dynamically coupled with the mechanical properties of the body …

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 …

The drag–thrusttransition and wake structures of a pitching foil undergoing asymmetric
sinusoidal oscillation are numerically investigated for foil thickness-based Strouhal number …

In this paper, we numerically investigate the propulsive performance of three-dimensional
pitching flexible plates with varying flexibility and trailing edge shapes. We employ our …

Experimental studies are conducted on a rotationally oscillating cylinder with an attached
flexible filament at a Reynolds number of 150. Parametric studies are carried out to …
