摘要
结合二期工程需要，通过喷头物理模型试验，研究流量、喷口射流角度和喷口孔数等因素对喷头局部阻力系数的影响。
The design flowrate of Shanghai second phase sewage disposal project is 1 7 million t/d.In order to increase the initial dilution ratio of near region,it is necessary to distribute sewage flow non uniformly among upfolw tubes of diffusers.But there is no approximate method for calculation minor loss coefficient of the spray nozzle available till now.So impact of some factors,such as flowrate,angle of jet port and numbers of ports on the minor loss coefficient of spray nozzles was studied through the physical model experiments. \ \
