용존공기부상조 내부유동의 전산유체해석 연구

Dissolved Air Floatation (DAF) process is one of sewage/waste water carriage methods. Purifying process is makes floating matter from sewage/waste water and air bubble. This study focused on basic research step to purifying industrial sewage using DAF process. For this study, Computational Fluid Dynamics (CFD) method was used. Commercial CFD software ANSYS FLUENT V.14.5 was used for multiphase flow analysis between sewage and air bubble in this study.
