Aerodynamic responses of rectangular plates with different aspect ratios during flapping motion were simulated using a three dimensional unsteady panel code. The three-dimensional effects during plunging and pitching motions were then analyzed. The results demonstrated that the added mass only contributes to the instaneous lift force. The amplitudes of lift forces induced by added mass effects would decrease with a decreasing aspect ratio,but the time-averaged contributions were always zero…
