Abstract
This paper presents the flow of non-Newtonian fluids through sudden enlargements. The calculations are done by a code with the finished volumes. The stabilizing effect of the physical characteristic of the fluid is taken into consideration. In addition, we set as objective the influence of the main parameters like the index of structure of the fluid, the Reynolds number and the aspect ratio of the widening, on the evolution of the velocity profile, the length of establishment of the flow in front of the enlargement as well as on the recirculation zone. The results obtained were confronted whenever possible with results from other literature.
