Monte Carlo simulations are performed to investigate deposition phenomena of sticky particles that undergo diffusive, convective, and gravitational influences on a highly permeable surface. Deposited structures are studied in 3-D space using a Pelcet number as the key parameter. Fractal dimensions of the particle trajectory and deposit structure indicate that a transition from diffusion-limited to convection (and gravitation)-limited transport occurs at the Peclet number of Pe = 10− 0.84 = 0.146. Analysis of the lateral density shows three distinct regions of deposit structures (defined in this study): founding, grown, and progressing regions. A penetration depth is defined to explain the relationship between particle transport and the evolution of deposit structures.
