A Review of CFD Development and Application in Dissolved Air Flotation
Dissolved air flotation(DAF)is an important treatment method in the water treatment industry,which has the advantages of wide range of adaptation and low operating cost,but its complex three-phase system makes it difficult to study its internal.Computational fluid dynamics(CFD)technology guides reactor design by numerical simulation,has low calculation cost and high data accuracy.Through a comprehensive review of the literature on the application of CFD in the development of DAF process,mainly discuss principle of flotation process,development of CFD method and optimization of air float reactor are ed,so as to highlight the characteristics of CFD method used at present and the latest development of numerical simulation tools.Finally,according to the summary of the content of the study,some suggestions for future research are put forward.
