摘要：
The k-epsilon, which has been modified to include the effects of mean streamline curvature, is used to predict the flow field and the flow-through curve (FTC) in two model settling tanks. Predictions are compared with measurements and with calculations using the standard k-epsilon-model. The results show the superiority of the modified turbulence model over the standard model to predict the flow field and mixing characteristics. All calculations were carried out on a personal computer.
