Review of Dolphin Hydrodynamics and Swimming Performance

  title={Review of Dolphin Hydrodynamics and Swimming Performance},
  author={Frank E. Fish and James Rohr},
Abstract : The principal objective of this project was to preform a comprehensive review of performance, kinematics, and swimming hydrodynamics by dolphins and other cetaceans. This report describes information obtained from the available literature including published research and technical reports from English-speaking and Russian sources. The project team specifically studied routine and maximum swimming speeds, morphological design related to hydrodynamic performance, drag reduction… 

Hydrodynamics of undulatory underwater swimming: A review

It is recommended that further research is required to fully appreciate the complexity of UUS and examine how humans can further optimise performance.

Dolphin-like Swimming Modeling for a Biomimetic Amphibious Robot

Abstract This paper focuses on a dolphin-like swimming hydrodynamics problem for a biomimetic amphibious robot capable of both fish- and dolphin-like swimming modes. A Lagrangian reduction has been

Optimized design and implementation of biomimetic robotic dolphin

An overall design procedure for a free-swimming, radio-controlled, multi-link biomimetic robotic dolphin mimicking dorsoventral movement is described, which shows some promising performance in aquatic environment.

Modeling and simulation of surface-and-dive behavior of a bottlenose dolphin

The results of the model's computer simulations match the previous reports on the dolphins' buoyancy, depth profiles, and speeds during ascent, descent, and porpoising activities.

Optimal Strouhal number for swimming animals

Modeling, simulation, and development of a robotic dolphin prototype

Abilities of sea animals and efficiency of fish swimming are a few of the impressive solutions of nature. In this paper, design, modeling, simulation and development studies of a robotic dolphin

into optimality and resonance in fish swimming.

This paper provides analytical insight into the hypothesis that fish exploit resonance to reduce the mechanical cost of swimming. A simple body-fluid fish model, representing carangiform locomotion, is

Propulsive Performance of Dolphins —Estimation from Analysis of Standing Swimming—

In the standing swimming of dolphins, which is often seen in aquariums, the total weight of the body is supported by the caudal fin in the water. It is clear that the thrust generated by the fanning

A Review: The Development of Flapping Hydrodynamics of Body and Caudal Fin Movement Fishlike Structure

This paper presents the historical development of description on how the flapping hydrodynamics of fishlike structure grows from infancy to the current state, particularly for the structure in which

The optimization of a dual foil flapping device

Abstract : Aquatic animals, such as dolphins and tuna, have the ability to swim and maneuver at much greater capacity than any man-made device. If their propulsion methods could be replicated



Observations of Dolphin Swimming Speed and Strouhal Number.

To record maximum dolphin swimming speeds sustainable for several seconds with free-ranging and captive dolphins utilizing different motivational strategies, particularly the Strouhal number, which characterizes dolphin swimming motion.


This paper presents an overview of research carried out at the Maritime Research Institute Netherlands (MARIN) on the subject of human swimming. The results obtained of an experimental study relative

Kinematic characteristics of the swimming of certain aquatic animals

Data on the velocity and kinematics of the swimming motions of various fishes and cetaceans are of great practical interest for the industries dealing with such animals, and may also be used in

Note on the swimming deceleration of a dolphin

A series of decelerative swimming motions of a dolphin were recorded underwater showing that the animal decelerated more rapidly than could be accounted for by frictional drag. The theory of swimming

Power and Speed of Swimming Dolphins

Measured swimming speeds for dolphins of the Stenella-Delphinus morphology are analyzed and energy expenditure for swimming dolphins is entirely within expected ranges and no extraordinary mechanisms are necessary to explain observations.

Dolphin Hydrodynamics Annual Report FY 82.

Abstract : The biohydrodynamic characteristics of dolphins were investigated to determine the mechanisms used to attain drag reduction and the applicability of these mechanisms to marine vehicle

Hydromechanical Aspects of Fish Swimming

The swimming motions of large aquatic animals are fascinating to behold. Their impressive performance is too difficult for human beings to emulate, either with our bodies or with our machines, and we

Aspects of the Locomotion of Whales

MR. GAWN has revived interest in Gray's1 demonstration that the drag of a fast-moving small whale, treated as a rigid body, seems to demand far more power than its muscles could supply, even if the


Summary The power output and propulsive efficiency of swimming bottlenose dolphins (Tursiops truncatus) were determined from a hydromechanica l model. The propulsive movements were filmed as dolphins

Energy Storage by Elastic Mechanisms in the Tail of Large Swimmers—a Re-evaluation

Abstract Fish and cetaceans may use, like mammals, elastic mechanisms to reduce metabolic cost of locomotion. Such energy savings require a detailed tuning of material properties and the dynamics of
