In this paper, the novel Tensor Diffusion approach for the numerical simulation of viscoelastic fluids is introduced based on the idea, that the extra-stress tensor in the momentum equation of the flow model can be replaced by the product of the strain-rate tensor and a (nonsymmetric) tensor-valued viscosity. As potential advantage (which can be de...
In this work, the novel “Tensor Diffusion” approach for simulating viscoelastic fluids is proposed, which is based on the idea, that the extra-stress tensor in the momentum equation of the flow model is replaced by a product of the strain-rate tensor and a tensor-valued viscosity. At least for simple flows, this approach offers the possibility to r...
An improved understanding of nonlinear elastic effects of rubber polymers involving very high relaxation times is of intensified interest, while the description and simulation of such flows is still a challenging problem. The present work "Evaluation of nonlinear differential models for the simulation of polymer melts" evaluates the capability of c...
