Solid Particle Movement Simulation in a Quiescent Container Based on Discrete Element Method Using CFDEM
AI summary Read the abstract
This study used the Discrete Element Method to simulate how solid particles, including microplastics, move through still water, modeling the physics of their settling and transport behavior. Accurate movement simulations help scientists predict where microplastics accumulate in aquatic environments, informing cleanup strategies and exposure assessments.
There has been an increased interest over the past few decades from the engineering and scientific community regarding the transportation of microplastics in open water environments. As a result of the number of processes involved in the movement and behavior of...
