A computational model of aquatic animal locomotion. (English) Zbl 0641.76140

Summary: A computational model of the swimming of a neutrally buoyant organism undergoing deformations within a region of fluid is presented. The fluid is regarded as viscous and incompressible and the organism as a massless, elastic boundary immersed in this fluid. Fluid quantities are represented on a grid (Eulerian description), and the immersed boundary is represented by a discrete collection of moving points (Lagrangian description). Computed results are presented, along with comparisons with previous asymptotic analysis.
