Abstract

We consider steady state and time‐dependent flows of chemically reactive polymeric systems in two‐dimensional geometries. A numerical simulation tool is proposed for predicting the evolution of the macroscopic velocity, temperature, stress and species concentration fields in such flows. We formulate a general mathematical model on the basis of the first principles of continuum mechanics, which includes a description of the non‐liner coupling between kinematics, heat transfer and chemical kinetics. The resulting set of non‐linear partial differential equations is solved numerically by means of appropriate finite element techniques. We have implemented the resulting numerical model in the general‐purpose POLYFLOW^R^ software developed in Louvain‐la‐Neuve, Belgium. Simulation results for various steady state and time‐dependent reactive flows are reported.
