“…The trajectories and distributions of the inclusions (1 µm~50 µm) were simulated using the Discrete Phase Model (DPM). In the model, the density of inclusions is 3000 kg/m 3 , and the diameter distribution of particles is discontinuous and is divided into 11 sizes, including 1,5,10,15,20,25,30,35,40,45,50 µm. In the integral Lagrangian coordinate system, the trajectory of an inclusion is described by the particle force differential equation.…”
