摘要
采用非定常势流理论,对高游速海洋动物所具有的新月形尾推进进行了分析,着重考虑了推进力能量的频率特性,并理论估算了一种海豚的实际游动状况。
Based on the unsteady potential flow theory, the lunate-tail swimming propulsion of fast ocean animals is analysed in this paper. The dependence of propulsive energetic quantities upon undulation frequency is particularly considered, and performance estimation of a porpoise is given.
