Abstract
The understanding of the physics of flapping flight has long been limited due to the obvious experimental difficulties in studying the flow field around real living thing. In this study the three-dimensional numerical simulation based on non-inertia reference was performed. The object motion is computed by the momentum equation using pressure calculated by the flow computation. And two-dimensional velocity field around the flat plate swinging of pendulum was measured quantitatively. We show that the data can be used for quantitative studies, such as lift and drag prediction.
