The phenomenon of dust particles surface
deposition in the fibrous medium showed the dendrites structures, which had
been confirmed and could be visualized by using computer technology for better
understanding particle deposition behavior on filtration process of fibrous
media. The pseudo-random movement model was used and the impact of particle inertia
movement and diffusion movement on the dust cake growth process in the fibrous
filtration media surface were studied by simulation. The simulation method and
programs were introduced in detail in the paper, and the result simulation of
particle deposition was in good agreement with experimental test result. The
results showed that more irregular the dust cake morphology structure was, the
greater the dust particles dispersion was and the greater dust cake porosity
was.
