In order to imitate tune tail fin better , a flexible fin only in chordwise is considered . results shows that flexibility can increase the propulsive efficiency and cause small decreases in the average thrust compared with a rigid caudal fin with similar motion . next , a comparison between the rectangle fin and the lunate fin is given 為了使數學模型更貼近生物模型,本文又將尾鰭處理為只考慮弦向變形而不考慮展向變形的柔性體,兩者對比的結果表明,柔性翼使得平均推力減小,但是,對具有相同推力的柔性翼比剛性翼具有更高的效率。
