When a thin flat plate is released in still air, the plate automatically sets into a rotational motion. This phenomenon is called autorotation. In this state, it is supposed that vortex shedding and unsteady fluid-dynamic forces interact each other. In this study, we carried out the numerical simulation of flow around a rotating elliptic cylinder in a uniform flow by discrete vortex method and comparison with the drag and lift coefficients calculated by finite-volume method and complex potential theory. The results show that the vortex shedding effect on the fluid-dynamic forces at the region between -50 degree phase and -180 degree phase for drag coefficient and at the region between -15 degree phase and -140 degree phase for lift coefficient.
