Therefore, the variations of simulated LRTD curves and experimental GRTD curves are consistent at varying [Q.sub.v].
The density function curves of the simulated LRTD and experimental GRTD at varying screw speed (N) are shown in Fig.
Figure 11 shows the density function curves of the simulated LRTD and experimental GRTD with different screw configurations.
With the indirect verification method, the simulated LRTD and the experimental GRTD, and the simulated LART and the experimental GART were compared to prove the reliability.
The trends of experimental GRTD and simulated LRTD were similar, and based on this, the GART and LART at different process conditions are in similar trends, which indirectly verified the reliability of simulation.
