Relative particle concentration profile at the PEL predicted from our pore entrance model compared to a Boltzmann probability for different particle sizes: (a) λ = 0.10; (b) λ = 0.30; (c) λ = 0.50; (d) λ = 0.80. Simulations were repeated with 102 particles for each particle size, initially placed at Xinitial = −5 and evenly distributed between −5 < Yinitial < +5. The radius of curvature of the pore entrance, rc/(h/2) = 1.
