Abstract

Experimental investigation of the details of particle deposition in fibrous filters is extremely difficult due to the nature of the filter media. Typically, fibrous filters are composed of fibers that are only a few microns in diameter. The fibers are randomly distributed in a plane that is approximately at right angles to the flow direction with a mean spacing of the order of 10 to 100 fiber diameters. Numerical simulation of the filtration process offers an attractive alternative to the experimental approach. In this paper such a simulation will be described. The present study considers the influence of an electric field on dendrite formation. Three-dimensional graphical representations of simulations with and without an electric field are presented, and the differences in dendrite structure discussed. A comparison with a two-dimensional model is also made.
