| Popis: | The crude oil is a non-Newtonian fluid presenting, during its flow, phenomena which cannot be represented by the traditional models which considers the homogeneous fluid hypothesis. Hence, it is necessary to take into account the microstructure characteristics of crude oil in the behaviour law, what is more realistic. The application of a non-linear differential model in the case of crude oil flow won't be adopted. This paper deals with the modelling approach resulting from rheology of the polymer solutions. The Model of Phan-Thien and Tanner (MPTT) is considered in this paper. However, this model presents certain restrictive assumptions which seem non representative of the observed phenomena. The impact of the modification of one of these assumptions was studied and no modification on the computed stress results was observed. The obtained results of stresses are presented and discussed. |
