    Abstract
  • This paper mainly addresses the thrust and lift characteristics of underwater symmetrical flapping foils by using the numerical computation method, analyzes the hydrodynamic of the flapping foils with different Strouhal num-bers, and summarizes the influences of the profile parameters and related factors on the flapping foils′ propulsive effect. The results show that the maximal thrust coefficient, the average thrust coefficient and the maximal lift coefficient de-crease linearly with increasing ratio of motion center to chord length; the parameters of profiles and the working condi-tions have different effects on the thrust and lift characteristics of the foils.
