Pilot and full-scale validation of thickener and feedwell modelling

Abstract

Advanced computational fluid dynamics (CFD) modelling techniques are well suited for examining suspension flow patterns within feedwells and thickeners from which improved design options can be developed and evaluated. However, the confidence to rely upon recommendations based upon CFD requires model validation, something that is not readily achieved without a major commitment of resources. This paper outlines a number of experimental validation procedures applied to test CFD models for different thickening zones as part of the AMIRA P266 “Improving Thickener Technology” series of projects. 1
