Abstract
⺠We measured particle penetration of smooth and rough crack experimentally. ⺠Fine particles concentration of 30 nm-500 nm were measured. ⺠At low pressure rough crack gives lower penetration than smooth crack. ⺠The results show that penetration is not sensitive to the roughness scales. ⺠A simple mathematical model accounting diffusion was developed for rough surfaces.
