| Abstract: | To study the effects of particle motion mechanism and size distribution on fractal dimension of dust cake structure,the process of aerosol particles deposition in fibrous filtration medium was simulated on basis of Diffusion-Limited Aggregation(DLA)improving model.In this study,effects of inertia movement and diffusion movement on particles deposition would be considered.In the mean while,ratio of inertia movement to diffusion movement was defined as Pe number.The results show that surface curve of dust cak... |
