| 摘 要： | 利用数值模拟的方法，引入欧拉双流体多相流模型及标准k-s紊流模型，模拟计算内循环厌氧反应器的三相流三维流场，并通过改变污泥颗粒密度及进水流量，针对固相流速及固含率的变化情况，分析条件的改变对流场的影响。研究结果表明，应用数值模拟方法可以获得内循环厌氧反应器内的流场特征；污泥颗粒密度及进水流量的改变对于反应器内污泥颗粒的流速及分布的均匀性有较为明显的影响。模拟结果对反应器的应用及优化设计具有一定的参考价值。

| Abstract: | The numerical simulation method, Euler-two-fluid muhiphase flow model and the standard k-e turbulence model were used to simulate the three-dimensional flow field in the internal circulation anaerobic reac- tor. For the distribution velocity and holdup characteristics of solid, the influence caused by the changes in the sludge particle density and influent flow was analyzed. The results show that the mathematical model can simulate the flow field eharacteristies within the internal circulation anaerobic reactor, and the ehanges obviously affect the velocity and distribution-uniformity of sludge particle within the reactor. The simulation results have the certain reference value for the reactor application and optimization design. |
