摘　　要：为了对可渗透反应墙墙体内水流速度及流态进行理论研究与分析,采用Fluent软件对可渗透反应墙墙体进行模拟仿真,构建墙体介质为陶粒.模拟仿真结果表明,墙体内填充介质陶粒内部流速缓慢,可以很好固定处理污染物的生物菌,同时也表明,该软件在微观环境下模拟可渗透反应墙内部流速及流态情况是可行的.In order to study and analye theoretically the flow velocity and flow pattern in the permeable reactive barrier,the software Fluent was used for the numerical simulation with permeable reactive bar- rier constructed by the medium of ceramic. The results of simulation showed that. the ceramic filled in the permeable reactive barrier flow slowly, which can well fix the biological bacteria for treating contami- nants.At the same time,it also showed it is feasible by using the software to simulate the flow velocity and flow pattern in the permeable reactive barrier in the micro environ-ment.
