This book presents a novel method for the numerical simulation of swimming animals. It includes a review of the hydrodynamics of swimming, a description of the CFD model adopted, and a description of the results obtained by applying this model to the cownose ray. This method is developed for the open-source software OpenFOAM and relies on an overset mesh. A custom library is added to the solver to include the equations of the kinematics of the animal under investigation, combining the deformation of the fish fins with the computed displacement and rotation of the animal's body. The presented method helps investigate the dynamics of any animal moving in a fluid, provided that its kinematics is known, and in this work, it is applied to investigate the hydrodynamics of a cownose ray. This book is intended for researchers and engineers who aim to deeply understand the hydrodynamics of fish swimming and to design bioinspired autonomous underwater vehicles or novel propulsion systems.

Movement and locomotion have always been key activities for all animals, being related to the most crucial life functions: retrieving food, facing environmental issues and mating. Humans developed complex upper arms movements and bipedal gaits in order to move and locomote. To enhance their performance, they started inventing smart passive mechanical tools. This need arose from intrinsic limitations of their muscle–joint–bone systems and metabolic power availability. Newly invented devices were mainly introduced in order to cope with such constraints. The aim of this Special Issue is to advance knowledge regarding symmetry, biomechanics and energetics of passively assisted human movement and locomotion.

From a mechanical perspective, an animal's shape and the topological connection of its organs are important factors in locomotion. This book describes the physical relationships between form, habitat, way of life, and movement in living creatures. It includes in-depth mechanical and mathematical analyses of the way in which creatures move about, and it also investigates dispersal modes of plants and animals within the framework of flying and swimming. The book is written from the viewpoint of mechanics, specifically fluid dynamics and flight dynamics, rather than from that of physiology and ecology. It will prove a useful reference for aeronautical and mechanical engineers as well as for biologists who use mechanical analyses in the study of behaviour, function, and locomotion.

This volume developed from a Workshop on Natural Locomotion in Fluids and on Surfaces: Swimming, Flying, and Sliding which was held at the Institute for Mathematics and its Applications (IMA) at the University of Minnesota, from June 1-5, 2010. The subject matter ranged widely from observational data to theoretical mechanics, and reflected the broad scope of the workshop. In both the prepared presentations and in the informal discussions, the workshop engaged exchanges across disciplines and invited a lively interaction between modelers and observers. The articles in this volume were invited and fully refereed. They provide a representative if necessarily incomplete account of the field of natural locomotion during a period of rapid growth and expansion. The papers presented at the workshop, and the contributions to the present volume, can be roughly divided into those pertaining to swimming on the scale of marine organisms, swimming of microorganisms at low Reynolds numbers, animal flight, and sliding and other related examples of locomotion.

An interdisciplinary study is continued to investigate the energetics and hydrodynamics of fish swimming involving transfer of biochemical energy through the rate of muscular working to the final stage of delivering the hydrodynamical power. Comparison between the drag coefficient and the power coefficient available for swimming, converted from data on metabolic rate with estimated muscle efficiency and hydromechanical efficiency, indicates their dependence on the Reynolds number according to a well defined similarity law. The range of their magnitude appears to provide a satisfactory resolution of Gray's paradox. (Author).
