| 摘 要： | 结合厦门污水排海工程进行了扩散器模型试验研究。模拟了污水和海水密度差，在全面研究了扩散器主要参数（竖管间距、喷孔个数、喷射角和喷孔平面布置等）与表层初始稀释度的关系的基础上，建议优先采用较多喷孔，增大竖管间距的布置，以节省工程投资；采用逆模型技术模拟了环境水体横向流动的作用；研究了多孔扩散器喷孔雷诺数对表层初始稀释度的影响，提出了满足相似要求所需的临界喷孔雷诺数；研制了相应的试验设备系统。

| Abstract: | he influence of diffuser parameters.including the riser spacing , port number in a riser,injection angle and port arrangement.etc. ,on the surface initial dilution is experimentally investigated .The relative density difference between the effluent and the sea water in the medel is the same as that in the prototype. and the effect of the cross current is simulated by an inverse model technique. Based on the result analysis,the arrangement with more ports in a riser and less riser spacing is suggested to save construction cost. The relationship be-tween the Revnolds number based on the pot diameter and veIocity, and the surface initial dilution is also explored, and the critieal Reynolds number is proposed, |
