摘要:

In previous papers, Monte Carlo simulations of the Knudsen diffusion of gases in porous solids having convex or concave pore walls have been performed. In the present paper, molecular trajectories inside pores are computed in the Knudsen region to obtain both collision density and collision numbers. It was found that these parameters were strongly dependent on the pore structure. The results obtained here will have applications to reactive flow and heterogenous catalysis.
