Abstract

Abstract

In the non-inertial coordinates attached to the model wing, the two-dimensional unsteady flow field triggered by the motion of the model wing, similar to the flapping of the insect wings, was numerically simulated. One of the advantages of our method is that it has avoided the difficulty related to the moving-boundary problem. Another advantage is that the model has three degrees of freedom and can be used to simulate arbitrary motions of a two-dimensional wing in plane only if the motion is known. Such flexibility allows us to study how insects control their flying. The results show that there are two parameters that are possibly utilized by insects to control their flight: the phase difference be tween the wing translation and rotation, and the lateral amplitude of flapping along the direction per pendicular to the average flapping plane.
