Wall Boundary Layer’s Viscosity Definition in the Forming Equipment Channels for Polymers Processing

The research objective is definition of the processed polymeric material melt properties in a wall boundary layer of working equipment channels. Setting the slip coefficient, that provides a linear relation between the viscosity in the boundary layer and the slip coefficient which often don't correspond to reality is a standard procedure in one of the most common polymer melts flow numerical simulation software package Ansys Fluent.

The discrete mathematical models for calculation of elastic-viscid-plastic environments with variable compressibility at thermopower loadings

In this paper, we construct the universal correlations of mechanics of continuous environments on the base of moment chart of finite elements. They allow designing the thermostress state and the processes of processing and formation of such nonlinear working environments as polymers fusions, friable and plastic masses in the products, given that hardening and the influence of remaining tensions on the properties of the end products are considered.
