Locomotion and control of a self-propelled shape-changing body in a fluid
Résumé
In this paper we study the locomotion of a shape-changing body swimming in a two-dimensional perfect fluid of infinite extent. The shape-changes are prescribed as functions of time satisfying constraints ensuring that they result from the work of internal forces only: conditions necessary for the locomotion to be termed self-propelled. The aim of this paper is several folds: First, it contains a rigorous framework for the study of animal locomotion in fluid. Second, it makes clear the connection between shape-changes and internal forces. Third, it contains the first theoretical result (to our knowledge) of control for a swimming body in an ideal fluid.
