Simulating Deposition of Aerosol Particles on Single Fiber Surface
Simulating Deposition of Aerosol Particles on Single Fiber Surface
摘要
Abstract
The stochastic simulation method, based on the concept of control window and the numerical solution of the Langevin equation, is applied to solve the deposition problem of particles from the flowing suspensions onto a fiber collector. Using the Kuwabara model to characterize the flow field, the effects of Stokes number, interception parameter, packing density, particle size distribution on the collection efficiency, and the deposition morphology of particles onto a collector areexamined. The morphology of deposit obtained in the simulated results agrees well with experimental observations. The estimation of the initial collection efficiency through the simulations considers that the deposited particles are in good agreement with published experimental data. In addition, the collection efficiency of particles increases in a wider particle size distribution region.关键词
