Recent years, Lattice Boltzmann Method (LBM) has become one of the promising schemes for incompressible flow simulation. Since LBM is based on Cellar Automaton, its original version is formulated on uniform homogenous mesh system. Applying general coordinate system enables allows flow computation around arbitrary body shape with sufficient accuracy in the boundary layer. In this present study, flow around cylinder was simulated for wide range of Reynolds number. Computational results show that the present LBM code can successfully predict drop in the drag coefficient at Reynolds number 10(exp 5) to 10(exp 6), which is known as 'drag crisis' from the experimental data.
