Fig. shows three simulations of F2 in the sequential injection. The colors of the AM particles show the distribution of AM particles in the extruder with rotation speeds of 500 rpm, 2500 rpm, and 5000 rpm. The grey zones in these figures represent BC particles. The coordination number of the AM particles was analyzed at t = 70 𝑀 𝛥𝑡. Most of the AM particles in the simulation with a 500 rpm rotation speed still stay in the extruder barrel. After increasing the rotation speed to 2500 rpm, the AM particles were better distributed throughout the system but accumulated and clogged at the end of the extruder barrel. In the 5000 rpm simulation, the AM particles are homogeneously distributed throughout the system.
