A finite-volume fast diffusion-limited aggregation model for predicting the coagulation rate of mixed low-ionized system

A finite-volume fast diffusion-limited aggregation model for predicting the coagulation rate of mixed low-ionized system

Accompanied with the changing of coagulation time, the micro-structure of aerogel can be controlled by adding Polyacrylic acid (PAA) into sol system. We simulate the process of particles aggregation contains attracting molecular chains based on diffusion-limited cluster aggregation (DLCA). Compared...
