摘要：
We present two-dimensional lattice Boltzmann simulations of flow past a cylinder which show that the drag coefficient is proportional to the factor multiplying the convective term in the Navier-Stokes-like equations obtained for Boolean lattice gases and for certain lattice Boltzmann models. With the correct expression for the drag coefficient, we show that the results of previous Boolean lattice-gas studies of drag agree with experiment and with each other.
