The performance of a rectangular slit impactor was simulated using the three-dimensional computational fluid dynamics (CFDs) computer program CFX-4.4. The characteristic impactor efficiency curve obtained from the simulations was compared with the experimental results. A sensitivity study was carried out to investigate the effect of (a) the total number of particles used for the simulation, (b) gravity in the simulation, and (c) ultra-Stokesian drag on the efficiency curve predictions. The simulation predictions for each of the above cases are presented along with the experimental data and the results are discussed. Results obtained from the simulation are seen to be in good agreement with experimental data, validating the particle transport model implemented in CFX-4.4, for laminar flow conditions. 2005 Elsevier B.V.
