Finite Element Simulation and Error Estimation of Polymer Melt Flow
Accuracy analysis is fundamental to ascertain the reliability of a numerical solution of any industrial operation. The analysis is often complex due to different error sources. In this work, two strategies to assess the discretization errors is discussed: (i) Richardson extrapolation and (ii) a posteriori error estimation based on projecting/smoothing techniques. The former utilises three neste...

15 صفحه اولIndividual entanglements in a simulated polymer melt.
Since the first theories of rubber elasticity, the notion of entanglement between polymer chains has been a central component [1]. Conceptually these entanglements are viewed as discrete constraints that limit the configurations of the chains, reduce their randomness, and thus contribute to the entropic stress in the rubber. These same entanglements are thought to be present in polymer melts. H...
متن کاملShear viscosity of a crosslinked polymer melt
– We investigate the static shear viscosity on the sol side of the vulcanization transition within a minimal mesoscopic model for the Rouse-dynamics of a randomly crosslinked melt of phantom polymers. We derive an exact relation between the viscosity and the resistances measured in a corresponding random resistor network. This enables us to calculate the viscosity exactly for an ensemble of cro...
متن کاملFlow-induced correlation effects within a linear chain in a polymer melt.
A framework for a consistent description of the flow-induced correlation effects within a linear polymer chain in a melt is proposed. The formalism shows how correlations between chain segments in the flow can be incorporated into a hierarchy of distribution functions for tangent vectors. The present model allows one to take into account all the major relaxation mechanisms. Special cases of the...
