Abstract

A simple method has been developed to track the three-dimensional motion of a small particle convected in a stirred tank for about 1 h. Different flow patterns induced by a Rushton or a pitched blade turbine have been studied. The results have been compared with known results obtained by conventional techniques. Several tools which have been proposed for this purpose give rise to new insights and interpretation of transport and mixing processes in stirred tanks for engineering applications. On a mis au point une methode simple pour suivre le deplacement tridimensionnel d'une petite particule dans un reservoir agite pendant environ 1 heure. Differents profils d'ecoulement induits par une turbine Rushton ou a pales inclinees sont etudies. Les resultats sont compares avec des resultats connus obtenus par des techniques traditionnelles. Plusieurs outils proposes a cette fin permettent de mieux comprendre et interpreter les procedes de transport et de melange dans les reservoirs agites pour des applications d'ingenierie.
