A Comparative Mechanophysiological Study of Fish Locomotion with Implications for Tuna-Like Swimming Mode.

摘要

An interdisciplinary study is continued to investigate the energetics and hydrodynamics of fish swimming involving transfer of biochemical energy through the rate of muscular working to the final stage of delivering the hydrodynamical power. Comparison between the drag coefficient and the power coefficient available for swimming, converted from data on metabolic rate with estimated muscle efficiency and hydromechanical efficiency, indicates their dependence on the Reynolds number according to a well defined similarity law. The range of their magnitude appears to provide a satisfactory resolution of Gray's paradox. (Author)
