| 摘 要： | 根据能量方程能确切地反映气液双相流动中的不可逆损失这一特点,在劳伦兹能量模型的基础上,本文提出了新的截面含气率的计算方法,从而得到了修正分相能量模型,并以此作为处理数据的依据。作者用三块不同截面比的安装在管径为50.8mm的管道上的锐缘孔板,分别与口径为100mm的椭圆齿轮流量计组合进行了试验,试验结果表明,利用此模型处理数据时,不必考虑孔板截面比的影响,也不必考虑被测介质干度范围的影响。在本试验的范围中,(0.00111

| Abstract: | As the irreversible loss in gas-liquid two-phase flow can be described exactly in terms of energy equation, the authors provide anew method in calculating void fraction based on energy model proposed by Lorenzi. An improved energy flow model has now been obtained to treat the experimental data. Three different orifices were used respectively to combine with an oval gear flowmeter in the test. Experimental results indicated that, when the improved energy flow model was used to treat the experimental data, nither the effect of area ratio of oriffice nno the effect of range of quality should be taken into consideration. In the range or this test, (0.00111
