Differential viscoelastic isothermal problem:

We tested the same probleme (Mixing) with viscoelastic fluid. In this case, we must choose a viscoelastic model. The following results are obtained using Maxwell model.

This modelisation of constraints is: Tau + Lambda * Tau' = 2 eta * ( D + Lambdar D')

         

       

                       

                       The density is the same in both cases. Results show there is no difference of velocity. The only difference is the pressure field.
