What mechanisms of flow control do animals use to enhance hydrodynamic performance? Animals are capable of manipulating flow around the body and appendages both passively and actively. Passive mechanisms rely on structural and morphological components of the body (i.e., humpback whale tubercles, riblets). Active flow control mechanisms use appendage or body musculature to directly generate wake flow structures or stiffen fins against external hydrodynamic loads. Fish can actively control fin… Expand
Mechanics of Pectoral Fin Swimming in Fishes
TLDR
This chapter describes how deforming bodies and fins interact with the surrounding fluid to generate propulsive forces, and which measures of swimming performance are most important in influencing how fishes exploit resources in their environment. Expand
Hydrodynamic flow control in marine mammals.
TLDR
The morphological features of marine mammals for flow control can be utilized in the biomimetic design of engineered structures for increased power production and increased efficiency. Expand
Mechanisms underlying rhythmic locomotion: body–fluid interaction in undulatory swimming
TLDR
A model for the body–fluid interaction in undulatory swimming of leeches, where the body is represented by a chain of rigid links and the hydrodynamic force model is based on resistive and reactive force theories, is developed. Expand
Fish locomotion: kinematics and hydrodynamics of flexible foil-like fins
The fins of fishes are remarkable propulsive devices that appear at the origin of fishes about 500 million years ago and have been a key feature of fish evolutionary diversification. Most fishExpand

TLDR
How modifications to control surfaces can alter flow and increase hydrodynamic performance is reviewed to alter flow to increase lift, reduce drag and enhance thrust in the case of propulsive fin-based systems in fishes and marine mammals. Expand

The study of fish locomotion provides a rich source of inspiration for the design of robotic devices. Fish exhibit an array of complex locomotor designs that involve both diversity of structures usedExpand
Hydrodynamic Performance of an Undulatory Robot: Functional Roles of the Body and Caudal Fin Locomotion
TLDR
A biomimetic robotic fish that travel along a servo towing system is implemented, which can be regarded as “treadmill” of the model, and it is shown that the wake structure behind the robotic swimmer is more sensitive to the Strouhal number and caudal fin pitch angle. Expand

Fish physiologists use experimental hydrodynamics techniques to visualize and quantify the way water moves around swimming fishes. Studying water motion provides information about forces that fishesExpand
Hydrodynamics of Undulatory Propulsion
TLDR
This chapter focuses on recent experimental hydrodynamic data on undulatory locomotion in fishes, and provides a general description of the major theoretical model of undulatory propulsion, and represents a significant new arena of investigation. Expand
The Pneufish: A soft-robotic, pneumatic model for studying fish locomotion
Fish swim using a combination of active and passive movement [1, 2]. The most common type of active swimming is characterized by muscles producing an undulatory wave down the body of the fish. TheExpand

Function of pectoral fins in rainbow trout: behavioral repertoire and hydrodynamic forces
TLDR
Despite its traditional categorization as a propulsor of limited functional importance, the salmoniform pectoral fin exhibits a diverse locomotor repertoire comparable to that of higher teleostean fishes. Expand

TLDR
Quantitative flow visualization and electromyography is used to show that trout will adopt a novel mode of locomotion to slalom in between experimentally generated vortices by activating only their anterior axial muscles. Expand
Near-body flow dynamics in swimming fish
TLDR
The fish benefits from smooth near-body flow patterns and the generation of controlled body-bound vorticity, which is propagated towards the tail, shed prior to the peduncle region and then manipulated by the caudal fin to form large-scale vortical structures with minimum wasted energy. Expand

TLDR
Lateral impulse in the wake is estimated assuming that the flow field represents a slice through small core vortex rings and is shown to be significantly larger than forces estimated from the kinematics via elongated body theory and via quasi-steady resistive drag forces, indicating that unsteady effects are important in undulatory force production.

TLDR
Rainbow trout selectively activated only their anterior red axial muscles and abandoned the antero-posterior wave of red muscle activity that drives undulatory locomotion in uniform flow, which supports a previously proposed hypothesis that trout are not just swimming in the reduced flow behind a cylinder.

A hydrodynamic analysis of fish swimming speed: wake structure and locomotor force in slow and fast labriform swimmers.
TLDR
Two hypotheses relating locomotor stability, maneuverability and the structure of the vortex wake are presented and a potential hydrodynamic trade-off between speed and maneuverability that arises as a geometric consequence of the orientation of vortex rings shed by the pectoral fins is proposed.
