The hydrodynamic analysis of fish propulsion performance and its morphological adaptation
- 109 Downloads
The hydrodynamic performance of fish undulatory swimming has been studied by means of the linear three-dimensional and the non-linear two-dimensional waving-plate theories developed recently by the present authors. The morphological adaptation of the anguilliform mode, carangiform mode, and lunate-tail swimming propulsion in the biological evolution process of fishes has been understood tentatively from the point of view of hydrodynamic analysis.
