摘      要：The dynamic performance and wake structure of flapping plates with different shapes were studied using multi-block lattice Boltzman and immersed boundary *** typical regimes relevant to thrust behavior are *** is nonlinear relation between the thrust and the area moment of plate for lower area moment region and the other is linear relation for larger area moment *** tendency of the power variation with the area moment is reasonably similar to the thrust behavior and the efficiency decreases gradually as the area moment *** the mechanism of the dynamic properties is associated with the evolution of vortical structures around the plate,the formation and evolution of vortical structures are investigated and the effects of the plate shape,plate area,Strouhal number and Reynolds number on the vortical structures are *** results obtained in this study provide physical insight into the understanding of the mechanisms relevant to flapping locomotion.
