抄録

Flows around a pitching wing with a bending motion in a uniform flow are studied numerically. A finite difference method based on Marker and Cell (MAC) methods is used to calculate the two dimensional incompressible Navier-Stokes equations. The third order upwind finite difference scheme is used. Body-fitted grid generation with moving boundaries is used to obtain the numerical solutions of the flow fields. The effects on the flow field of Reynolds number, pitching frequency and bending angles are studied numerically. The effects on C_D of pitching motion and bending oscillation are obtained. The results shows that a thrust is generated on the pitching and bending wing.
