中文摘要:

为了预测紫外反应器的流场特性,利用CFD技术,分别采用标准k-ε模型、Realizable k-ε模型、低雷诺k-ε模型和雷诺应力模型(RSM)进行了水力特性的模拟。结果表明:在x=0,z=1cm以及x=0,z=83cm处,4种湍流模型对z向流速的模拟结果都较符合PIV实验数据,在x=0,z=15cm处,Realizable k-ε模型的模拟结果偏差较大,在x=0,z=64cm处,标准k-ε模型的模拟偏差较其他3种模型大。综合比较,低雷诺k-ε模型和RSM模型的模拟结果较为理想。

英文摘要:

In order to predict the flow field characteristics of UV disinfection reactor and enhance the accuracy of the modeling results, the paper utilized CFD simulation method and applied Standard k-ε model, Realizable k-ε model, Low-Re k-ε model and RSM model to simulate the hydrodynamic features.The results indicated that at the place of x=0,z=1cm and x=0,z=83cm, the simulation result of z direction of the four turbulence models accord with PIV experiment data on the whole. While at x=0, z=15cm and x=0,z=64cm, the simulation result of realizable k-ε model has large deviations. The results of Low Re k-ε model and RSM model are more ideal in hydrodynamic modeling.
