In the present work, a numerical study of 2D fluid mechanics in an abrupt contraction is made, for non-newtonian flow with Ostwald-de Waele type law of power. Two solution methods are used : finite volumes and finite elements methods. In the finite volumes method, the SIMPLE algorithm is used to solve the linear momentum and continuity equations. In the finite elements method , Fortran 90 language is used for writing our own program. In both methods, the behavior of the fluid, for different indexes of power, is studied. The calculations are made with rectangular variable mesh (method of finite volumes) and with mesh attached to the contour (method of finite elements).

Palabras clave : Non-Newtonian flow; finite elements method; finite volumes method.
