Abstract

Stirred tanks are widely used in various industries for mixing operations and chemical reactions for single- or multi-phase fluid systems. In this study, a numerical study was conducted to predict the mixing characteristics in a simple stirred tank. The flow in the model stirred tank was calculated utilizing the multiple reference frame (MRF) and the sliding mesh (SM) capabilities of a commercial CFD code (Fluent 6.2). The results of the flow simulation were analyzed in terms of the mixing efficiency, and the applicability of MRF and SM methods was also discussed.
