  • Abstract Using a 2-D lattice Boltzmann method coupled with a Lagrangian formalism, the present study develops a computational model to predict particle collection efficiency for nylon mesh screens. The deposition efficiencies for particles with diameters between 10 nm – 300 nm are examined as a function of the inlet velocity for three mesh screen pore sizes (60, 100 and 180 μm). Particle motion mechanisms include drag, Saffman lift, gravity and Brownian forces. Our results show good agreement between computed data and experimental measurement.
