In this paper, a ghost flow in lattice Boltzmann method is developed to simulate for curved boundaries. As such, a new formulation for airfoil boundary. Conditions is developed using a bilinear interpolation method. In this researched have been for two-dimensional fluid flow around airfoil (NACA 0012) And compare the results of the presented method are compared to those available in the literature from conventional numerical methods, and excellent agreement is observed. In recent years, several strategies have been proposed for dealing with complex geometry, curved boundaries to study particle-fluid interaction in the frame of lattice Boltzmann method. Curved boundary treatments have been suggested as a means of improving the accuracy of the stair-shaped approximation conventionally used in LBM simulations. This is presented to solve fluid dynamics. Based on the theory molecule kinetics, an extended Lattice Boltzmann equation is put forward to solve force in Reynolds number range that be applicative for Micro-Air-Vehicles (MAVs).
