The study of slag particle deposition process based on Monte Carlo simulation

The microscopic characteristics of particle deposition are critically important for the study of slag flow, particularly for semi-viscous particles. In this study, based on the disordered motion of particle deposition, a Monte Carlo (MC) simulation method was adopted to study the deposition, attachment and rebound process of particles. Considering the characteristics of the partial melting of semi-viscous particles, the collapse behavior and deposition probability of the deposition sequence were studied. The concepts of a rough surface layer and steady bottom layer were proposed. The results showed that the roughness of the deposition sequence increased with an increase in collapse height. Meanwhile, more particles were captured in the steady bottom layer; therefore, the time required for the steady bottom layer to stabilize increased. Considering the physical significance of the collapse height, the effect of the temperature on the deposition characteristics of the rough surface layer was studied.
