Abstract
Diffusion deposition of nanoparticles in model granular filters with different structures has been considered at low Reynolds numbers. On the basis of a three-dimensional flow field calculated for layers of granules, nanoparticle-collection efficiences have been determined for the granules in a wide range of the Peclet diffusion numbers. The interference of the layers has been studied, and approximation equations have been derived for calculating the pressure drop and the nanoparticle-collection efficiency.
