摘要：
The ground effect on flapping wing is investigated numerically based on the immersed boundary-lattice Boltzmann method. A NACA0012 airfoil is considered in this work. The airfoil executes oscillation along vertical direction near ground. The simulations have been carried out for some parameters including the distance between the foil and the ground and frequency of oscillation as well. The ground effect on the force behaviors and vortex structures is analyzed. The results achieved in this work can shed physical insight into the understanding of aerodynamics and flow structures for air vehicle flying near the ground or water surface. (C) 2013 The Authors.
