摘要:
在没有密度分层的容泄水体条件下,对某污水排海工程多孔喷头的射流特性进行了实验研究。文中介绍了不同排污流量和环境流速条件下,多孔喷头附近的流速场和污水场特性;并对出流平均稀释度作了分析。最后,还对该喷头周围的冲淤形态进行了探讨.文中所得的结果对实际排污系统的设计和进一步研究有一定的参考价值。

Abstract:
The jet behavior of a multinozzle head scaled from an existing engineering was investigated experimentally in a steady unstratified receiving water body. In the cases of different effluent discharges and ambient currents, velocity fields and wastewater zones near the port were systematically measured and data were processed; the average dilutions studied; and finally, the erosion and deposition near the nozzle head discussed. The results presented are applicable to sewage outfall designs.
Key words:  Multinozzle head  Jets  Average dilution  Characteristics of erosion and deposition.
