| 摘 要： | 本文采用紊流代数应力模型计算了明渠强迫掺气水流掺气设施后的两相流动，通过求解气相的质量守恒方程求得两相混合物的掺入浓度分布。算例与实验资料比较，结果基本吻合，表明这种模型是合理可行的。

| Abstract: | A mathematical model was devetoped to predict the air concentration profiles and other flow parameter for the air-water two-phase flow below an aerator. The air concentration was calculated by solving the conservation equation of air mass, and the turbulent stress was worked out by algebraic stresses model (ASM). The computational air concentration was compared with experimental data, and the result was in agreement. It shows that the present analytical approach was satisfactory. |
