Abstract

Based on the presented model for the impinging jet system, extensive theoretical analysis was made on particle deposition. Complete transport equations with consideration of gravity, van der Waals, and electrical double layer (EDL) interactions, as well as hydrodynamic interactions, were numerically solved. The influences of gravity, van der Waals, and electrical double layer interactions on the particle deposition rates (in terms of the Sherwood number) were presented. The results demonstrate that the asymmetric EDL interaction, which has been ignored in previous treatments, has an impact on the particle deposition rate. It was also found that the Sherwood number is strongly dependent on the characteristics of the particle-collector interaction energy profiles, such as the height of the energy barrier and the depth of the secondary energy minimum. Particularly, the effects of the height of the energy barrier and the depth of the secondary energy minimum on the Sherwood number for different Peclet numbers were discussed. In addition, a simple expression was derived for quantitatively estimating the contributions to the deposition rate due to particle diffusion, migration, and convection. With the aid of calculated particle concentration distributions, this expression can be used to understand the numerical predictions. Copyright 1998 Academic Press.
