摘要
从航运、施工、管理及水生生物回游等角度出发，提出采用多孔Ｔ型扩散器排放污水。根据多孔射流发展规律，分析Ｔ型扩散器排放近区流态特性，运用笔者所研制的数学模型进行模拟计算，预报Ｔ型扩散器排放近区轴线流速、浓度及稀释度的沿程变化规律，得出了相对动量和扩散器长度是影响污染物横向扩散的主要因素。
In this paper tee diffuser discharge wastewater is presented. The mathematical model and calculational method are used to predict the flow phenomenon of tee diffuser discharge. The developments of the centerline velocity, concentration and dilution are calculated. The length of the main current core, the transverse velocity and concentration are given. The kinetic energy of discharge and the length of tee diffuser are found to have strong influence on the characteristics of tee multiport diffusers.
