ABSTRACT: 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.
