| 摘 要： | 气-液两相流通过孔板的局部阻力计算是工程设计中有待于解决的一个问题。本文就这一问题提出了一种新的模型,并在低压空气-水两相流试验台上进行了试验验证。结果表明,计算与实验符合得较好。作者又将计算值与高压蒸汽-水系统的实验数据作了比较后发现,该模型亦基本适用于高压蒸汽-水系统。因此,本文提出的模型有较广的适用范围,其精度也能满足一般工程计算的要求。

| Abstract: | The calculation of local resistance of gas-liquid two-phase flow through an orifice is a problem pending solution in engineering design.A new model has been developed to solve the problem. The calculation on which the model is based has been verified by tests carried out on an air-water two-phase flow test-bed and is proved to be in good agreement with the experimental results. By comparing the value of the calculation with the data obtained from experiments of steam-water system, the authors found that, on the whole, this model fits in with the system of steam-water mixture. Therefore the model proposed covers a rather wide range of application and its calculation accuracy can meet the general requirement of engineering design. |
