Experimental and numerical analysis of performance of two fluted mixer designs
Popis výsledku v původním jazyce
In this paper, the effect of the Maddock mixer design on its performance in the single screw extrusion of High-density Polyethylene (HDPE) melt has been investigated experimentally on a special extrusion line equipped with a barrel having several glass windows as well as theoretically using a three-dimensional finite element method simulation. The red-green-blue spectral analysis has been used for the experimental quantification of the mixing efficiency, whereas a generalised Newtonian model (with Carreau-Yasuda viscosity function) and a viscoelastic modified White-Metzner model have been utilised in flow simulations. Based on the performed experimental work, it has been found that the mixer with no undercut wiping flight ('Closed' mixer) has a fastermixing/purging but a similar final mixing performance as the mixer with undercut wiping flight ('Open' mixer). It has also been revealed that the 'Open' mixer creates an unwanted dead zone (in the form of the stagnation layer of material
