A new spatial differential approximation in the lattice kinetic scheme is proposed. In the method, the first derivatives of macroscopic variables at a wall are calculated as the weighted mean values of finite difference approximations in calculable directions. Thus, there is no need to specify the normal and tangential directions at the wall. The lattice kinetic scheme with the present method is applied to simulations of flows in porous structures of many spherical bodies and of many fibrous bodies. The results indicate that the method can be effective and applicable to flow problems in complicated geometry of arbitrarily-shaped solid bodies.
