We present a three fields formulation of the Stokes problem with the following unknowns: (σ) over bar extra stress tensor, psi stream function and omega vorticity. This formulation is motivated by the Oldroyd model for viscoelastic flows. In fact, it appears that problems in ((σ...

Furthermore, the efficiency of many numerical methods used for the approximation of the solution for the flow of viscoelatic fluids necessitates, in the general case, that the extra-stress tensor is integrable. Then, we think that this example can be an interesting problem to test the ...

An implicit algebraic ...
Two-dimensional viscoelastic flows described by differential models employ three partial differential equations for calculating the components of the extra-stress tensor whereas an algebraic model requires only one partial differential equation to be solved. Therefore, algebraic models are attractive because ...
