Abstract
The present work is confined to deal with laminar flow of incompressible pseudoplastic fluid through a sudden expansion. An experimental study is carried out to measure the re-establishment length, the velocity and the pressure drop due to the enlargement. The basic equation governing this problem is integrated by means of a finite volume scheme using a non uniform staggered grid. The numerical results obtained are compared with experimental results and the agreement is shown to be good. 1. Introduction The problem of fluid flow through singularities, in particular through expansion or contraction pipes, has received much attention in literature[l- 4]. It is largely due to its technical interests in many engineering processes. The study of real fluids in food, chemical and
