Abstract
ABSTRACTSmoothed Particle Hydrodynamics was employed in the present two-dimensional simulations, thus the algorithms implemented for both continuous and dispersed phase share a common Lagrangian stencil. The results were benchmarked against those produced in earlier investigations of particle deposition resulting from the flow around a stationary square obstacle. The proposed numerical procedure also facilitates the investigation of the fundamental physics governing the transport of resuspended particles in the wake of a moving operator, e.g., inside cleanroom facilities. Aiming to illustrate this capability, the dispersion of neutrally suspended particles behind an impulsively-started plate has been numerically simulated. Two distinct particle dispersion patterns, characterized by different Reynolds numbers, have been obtained for this problem. Altogether the results have demonstrated the accuracy of the method and associated advantages for multiphase flow studies, especially in cases involving moving bo...
