A Remark on the Deviatoric Decomposition of Oldroyd Type Models
Original language description
Certain viscoelastic fluids can be described by the class of Oldroyd type models. In these models the viscoelastic extra stress tensor is computed from a tensorial evolution equation. In contrast to classical Newtonian fluids, this viscoelastic stress tensor has non-vanishing trace. It means that it contains not only deviatoric, but also spherical part. The aim of the present paper is to develop a reformulation of the Odroyd type model, where the deviatoric and spherical components are computed separately. It will be shown how such a deviatoric reformulation of an Oldroyd model can be derived and how it can be used.
