Abstract

<p>Solid–liquid two-phase flow was studied on inclined and bent settling plates. A 40% glycerol solution was used for the continuous phase, and 400 µm glass beads were used as the settling substance. In the visualization experiment, the fluid velocity vector of the continuous phase was obtained by the PIV method. In numerical analysis, the flow behavior was considered using the DEM method and CFD. Good agreement was found between the results of the visualization experiment and the numerical analysis. Furthermore, characteristic flow was observed around the bent section: the flow rate of the continuous phase was almost equal in the upper and lower layers in the initial state.</p>
