| Abstract: | Based on the unsteady incompressible potential flow theory, the swimming performance of the caudal fin is further studied. The effect of spanwise deformation of a caudal fin with moderate to large aspect ratio on its chordwise undulation propulsion, and the effect of closeness to the ground on the swimming performance of some bottom-living fishes are examined in this paper. |
