摘要
分别使用长度相同通径不同和通径相同长度不同的阻尼孔,在水介质条件下对其流动特性进行实验研究。实验结果表明:水介质阻尼孔流动特性实验值和理论值有较好的一致性,其中大通径的阻尼孔流动特性的稳定性更好,小通径阻尼孔流动特性波动比较大;阻尼孔长度对流动特性的影响很小,在较大的长径比范围内,可以忽略长度的影响。
In water environment, the flow characteristic of two series damping orifices, one with the same diameter and different length, the other with the same length and different diameter, were studied experimentally. The experimental results show that the experimental data agree well with the theoretical data. The results of the damping orifices with big diameter have Better stability, and the results of the damping orifices with small diameter fluctuate dramatically. The length has very small influence on the flow characteristic, so it can be neglected in a wide length-diameter ratio range.
