| For construction of non--linear mathematical model of dolphin tail fin motion an approach based on the double and vortical layers potentials theory, and also on the singular integral equations theory was applied. At that the three--dimensional effects and influence of thickness of the fin, and also of viscosity of the medium was neglected. Using the improved method of discrete vortices a non-linear, non-stationary, two-dimensional numerical model of dolphin tail fin motion, well describing known features of its work was constructed. It was revealed, that main mode of dolphin's swimming is characterized with minimal contribution of sucktion force into the thrust. |
