Microplastic (MP) transport patterns under open channel shear flow remain unclear. This study investigates the laws of MPs at various velocities, MP densities, sizes and concentrations in U-shaped experimental flume numerical based on Lattice Boltzmann Method (LBM). The results indicate that average horizontal particle velocity distances Polyvinyl chloride (PVC) Polystyrene (PS) particles increase with cross-sectional velocity, while vertical decreases it. total closely matches regardless variation size, density concentration. Formula-based analysis reveals acceleration spherical mainly depends size its consequent relative drag force term (RDFT) conditions a single type particles, but RDFT gravity (RGT) case concerning different types identical sizes. maximum PVC PS are both strongly correlated cross-section. correlation lowers concentration, is independent density. Our findings can provide reference for prevention control pollution rivers.
