摘　　要：基于Fluent软件,建立了曝气头射流求解模型,分析了流体内部分布情况。在入口流量12 m^3·h^-1、入口气体压力0.1 MPa以及出口背压为500 Pa的工艺参数条件下,分别对不同出口扩散管收缩角、液体进口直径及喉管长度条件下射流流体分布情况进行研究。分析了曝气头中心轴向位置上的流体运动速度和压力分布规律。分析结果可为实际工程应用中的曝气头相关优化工作提供数据支撑。Based on the software Fluent,the jet flow model of aerator was established,and the internal distribution of the fluid was analyzed.Under the conditions of inlet flow rate 12 m^3·h^-1,inlet gas pressure 0.1 MPa and outlet back pressure 500 Pa,the distribution of jet fluid in different exit diffuser angle,liquid inlet diameter and throat length were studied.The flow velocity and pressure distribution in the axial position of the aerator were analyzed.The analysis results can provide data support for the optimization of aerator in practical engineering application.
