Abstract

In according to the simplicity of the lattice Boltzmann method’s(LBM) algorithm and its benefits, it has been used as a successful method in computational fluid dynamics in the last decades. In this paper, LBM was used to simulate the flow over a cylinder. To analyze the application of LBM in simulation curved surface, different methods to compute drag coefficient were used. These methods are: momentum exchange, momentum exchange on the wall, stress integration, computing stress by velocity components. The result shows the ability of Lattice Boltzmann method to simulate curved surface.
