- Abstract:
-
Using the CFD (Computational Fluid Dynamics) software FLUENT, the three-dimensional shear effect of the melt section and the metering section of the rubber extruder of the single screw pin barrel is simulated for non-Newtonian fluids. By comparing the shear effect on the cross-section of the screw groove and the cylindrical section of different radii with and without pins, it is found that the pin can strengthen the shear effect on the rubber material in the extruder, which is conducive to reducing the stagnant zone of the root of the screw, and the more pins per row, the greater the shear effect on the rubber material; By comparing the volume-weighted average shear rate of the flow field in the entire fluid region, it is found that the pin can effectively increase the average shear rate by 14%~28%, and greatly reduce the shear inhomogeneity.
