GENERIC Compliance of a Temporary Network Model with Sliplinks, Chain-Length Fluctuations, Segment-Connectivity and Constraint Release

It is shown that a recently proposed sliplink theory for polymer melts is consistent with the two-generator, non-equilibrium thermodynamics formalism, GENERIC. The model was previously developed using the free energy as a generator for the dynamics. Its primary novelty is that it uses the monomeric density as a dynamic variable instead of as a parameter. By placing it in the GENERIC framework, I also derive an appropriate energy equation necessary for performing non-isothermal flow calculations. Using the algorithm already proposed and the results given here, it is possible to simulate the complete non-isothermal flow of linear, entangled polymeric fluids in complex geometries.
