Abstract:

Article Preview

In this paper, a comparison between the Liang model and the Cogswell model is made by using them to simulate numerically the boundary streamline and the region length during the entrance converging flow of polymer melts. The results show that both of them can properly describe the flow conditions. Furthermore, the Liang model can accurately describe the geometry effect on the boundary streamline, and by introducing the Bagley correction factor e and the slip factor ξ, it can also describe the changes of the region length more precisely.
