Mixture model are used to simulate the FLUENT velocity distribution and sludge concentration in a circular sedimentation tanks.The results show that the particle of different size can be set to be different phase,thus realize the three-phase numerical sim%采用FLUENT中多相流Mixture模型对辐流式沉淀池内流场、悬浮物浓度场进行模拟,经分析认为不同粒径的颗粒可设置为不同的相,据此实现了对沉淀池的三相流数值模拟。
