| 摘 要： | 本文通过实验研究 ,观察分析了相同β值 (弯管弯度 )弯管在水平平面内和竖直平面内两种不同安装位置 ,它们所得到的流量校正系数 C的差别 ;同时对不同β值 (弯管弯度 )的弯管在相同平面内的安装位置 ,所得到的流量校正系数 C的差别进行了比较 .通过实验数据的分析 ,指出弯管的流量校正系数 C,同其安装位置的不同 C值是有所差别的 ,根据实验结果及分析 ,认为强迫旋流理论比自由旋流理论较符合弯管内流体流动的实际 .

| Abstract: | In this paper,the difference of the coefficient \$C\$ is analysed under the conditions of the same \$β\$ (Elbow Flowmeter s degrees.)value,but in the different horizontal and vertical installotion positions. In addition,the authors compared the difference of the coefficient \$C\$ in different \$β\$ value but in the same installation position. The result pointed out that the elbow coeffieient \$C\$ is different from that in the different installation positions. Besides, it is suggested that the compel Vortex Theory is more practical than the Free Vortex Theory in elbow flow. |
