RESUMO

To clarify the fish swimming mechanism, hydrodynamics of a thin deformable body is studied by the method of plane sections. Simple formulas are derived for estimating the thrust and consumed power in the case of sinusoidal wave deformations of the body axis. Hydrodynamic characteristics of fish motion are estimated. Theoretical results are compared to experimental data.

Palavras-chave: hydrodynamics of a thin flexible body, fish swimming mechanism, method of plane sections, hydrodynamic characteristics of fish motion
