Study of Three-Dimensional Modeling for Fibrous Filters with Image Effect 2001-01-2515

A fibrous filter made from stainless steel wire net (SSWN) has been developed [1]. This paper studies a 3-dimensional modeling and computing method for the fibrous filters, with image effect based on the SSWN filter. It takes the exhaust aerosol of a diesel engine as a homogeneous, steady flow composed of exhaust gases and particulates. Under the effect of an electrical force field, the particulates deviate from other gas phase components and deposit on the fibers. Mathematical models for calculating the flow, the electric field, and the capture efficiency are presented in this paper. These mathematical models are used for calculating a two-layer SSWN filter model.
