	Abstract:Flapping wing have integrated functions like lifting ,hovering and driving, but manufacturing and design of the Flapping wing need full understand on the aerodynamic characteristics and lift generating mechanism. This paper will do some researches on the shedding vortex of trailing-edge of Flapping wing at the fixed section, which would be helpful to the understand of the aerodynamic characteristics and lift generating mechanism. The results shows that the researches on maximum value of vortex's circulation is significant to the lift generating.

	Abstract:The effect of the protuberances leading and tailing edges on the aerodynamic characteristics of a modified airfoil is studied using the large eddy simulations. A more gentle lift characteristic is obtained during stall. For angles of attack less than the baseline stall angle of a NACA0012 airfoil, a lift coefficient reduction was observed for the modified airfoil, while the lift coefficient increases up to 37% greater than that of a NACA0012 airfoil when the angle of attack is larger than the baseline stall angle of the NACA0012 airfoil.

	Abstract:A three-dimensional numerical investigation on cross-flow around a staggered tube bundle in a diamond arrangement at Reynolds number of 200 has been carried out. Depending on the spacing ratio (L/D) varying from 1.2 to 5.0, the flow configurations were classified into three basic regimes. The critical spacing ratio for transformation of flow configuration from narrow gap flow configuration to vortex impingement flow configuration of the cylinders was found to be at L/D =3.0, while a single bluff-body flow configuration was observed at L/D =1.2. The relation between the three-dimensional flow configurations and force characteristics around the four staggered cylinders shows that the variation of forces and Strouhal numbers with L/D are generally governed by such three flow configurations. It is concluded that the spacing ratio has important effects on the free shear layers development of the cylinders and hence have significant effects on the fluid force of the four cylinders with different spacing ratio.
