“…The description of Pawlowski 10 and Kohlgr€ uber and Wiedmann 5 is based on a dimensionless formulation of the volumetric throughput and the axial pressure gradient in completely filled screw sections (similarly to Ref. 11), where the dimensionless throughput _ V Ã is defined as the volumetric throughput _ V over the screw speed n and the nominal screw diameter D cubed…”

“…Pawlowski 10 showed that for single screw extruders and Newtonian fluids in the creeping flow regime, the axial pressure gradient is linearly correlated with the throughput, and described the correlation by an empirical model termed "pressure characteristic", based on dimensionless numbers. As the pressure characteristic is determined by the detailed screw geometry, the used empirical parameters are called "screw parameters".…”
