Simulation and Analysis on Three-dimensional Flow Field of Integrative Oxidation Ditch

LUO Lin~1,LI Wei-min~2,DENG Rong-sen~2,HE Ze-chao~3,WANG Tao~2ina; 2. School of Urban Construction and Environmental Engineering,Chongqing University, Chongqing 400056, China; 3. School of Chemical Engineering,Sichuan University, Chengdu 610065, China)  
Three dimensional k-ε turbulence mathematical model was used to simulate the flow field of integrative oxidation ditch, and moving mesh technology was used to simulate the power sources of brush running in the ditch. By comparison on the theoretical calculation data and test result, it was indicated that the result of mathematic simulation is reasonable. Furthermore, detailed analysis was made on the flow pattern in the ditch, and then the measures of optimization and improvement were proposed for current design from the view of hydrodynamics.)
