高压喷嘴流量系数的实验测定

MEASUREMENT OF DISCHARGE COEFFICIENTS OF HIGH PRESSURE NOZZLES THROUGH EXPERIMENT

本文提出了一种测定高压喷嘴流量系数的新型测试系统,利用这套测试系统可以测定高压液流通过不同类型喷嘴,喷入具有一定反压的气体环境中喷嘴的流量系数。本文提供了部分实验结果。实验表明,这套测试系统具有很好的实用价值。

This paper puts forward a new testing system for measuring the discharge coefficients of high pressure nozzles. The system can be used to measure discharge coefficient of different nozzles with high pressure spray under different air back pressures. Some experiment results are presented, which prove that the system is much practical.
