different methods to compute force over a cylinder by lbm

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.
