摘要

An Euler–Lagrange hybrid model to simulate liquid–solid two-phase flow with adhesion and particle growth is presented for the simulation of particle transport, agglomeration, and deposition. The numerical model is based on CFD–DEM with the inclusion of adhesion and particle resizing. The verification is by reproduction of literature results referring to particle settling, normal collision, oblique collision, and pile formation. The effects of adhesion and particle growth in liquid–solid flow considers an adhesive-weight ratio of \(5\cdot 10^{4}\) 5 · 10 4 and particles growing from 20 up to 40 μm. It is possible to evaluate the individual and combined influence of adhesion and resizing, leading to distinct particle transport patterns. The influence of flow rate is also evaluated observing that there is a competitive effect between solid dispersion and diameter resizing that eventually leads to a favorable condition for bulk agglomerates build up that outbreak the pressure.
