According to our simulation results, particle mixing efficiency clearly depends on the different ways of injecting the particles into the extruder. Two different behaviors in terms of mixing efficiency can be clearly seen by comparing the overall behavior of the curves between Fig. and Fig. : the simulations reach the long-time state (𝑡 ∈ [30 -70 𝑀 𝛥𝑡]) much faster for the simultaneous injection scenario than for the sequential one.
