| 摘 要： | 文章根据扬水曝气器曝气室的流体特性,在曝气室内气-液两相流体所受推动力和曳力平衡条件下,建立了一维两相流提水性能模型,并应用于同温层曝气器流体运动特性的模拟预测。结果表明:模型对同温层曝气器上升段气含率的估计值与实测值之间的误差限为±10%,对流体表观上升速度的误差限为±20%。这说明提水性能模型对同温层曝气器的流体特性模拟具有很强的适用性。 |
| 关 键 词： | 曝气室 同温层曝气器 气含率 水体上升流速 |

| Abstract: | Mathematic models of one dimensional gas-liquid two phase flow water-lifting performance for aeration chamber was established on the basis of balance condition of dynamic and drag force acted on gas-liquid two-phase mixture.The model was used to simulate and predict the liquid characteristics of hypolimnetic aeration.Results indicated that the errors between calculated results and tested results were respectively ±10% for gas holdup ratio in the rising cylinder,and ±20% for superficial liquid velocity,which proved that water lifting performance models are suitable to simulate liquid characteristics of hypolimnetic aeration. |
| Keywords: | aeration chamber hypolimnetic aeration gas holdup water flow rate |
