2-D and 3-D Numerical Simulation of High-Sludge Setting Tank in Water Treatment Plant

Abstract:

The 2-D and 3-D numerical model have been developed to predict flow state and outlet velocity distribution by FLUENT based on the high-sludge setting tank in a large scale water treatment plant in Chongqing, and physical model has been built to verify the rationality and accuracy of the models. With the comparison of the two models, the following results can be found: 3-D model is lower in computing efficiency; both of the flow state are in substantial, but the stream lines of 3-D model are more complex; The velocities of 2-D model are slightly higher, both of the velocity distributions and tendency are approximately identical in 5 to 6 meters and 14 to18 meters, but not the same in 6 to 14 meters. 3-D model is more reasonable and accurate compared with 2-D model.
