【摘要】 气油二相流是工程中常见的一种多相流,如何标定其含气率一直是气油二相流研究中的一个难点。本文通过对几种气油二相流含气率的标定方法研究,结合作者实践,分析了各种方法的特点,认为量简法、压力法及浮力法能方便、准确地用来对气油二相流含气率进行标定。更多还原

【Abstract】 Bubbly oil is a common kind of multiphase fluid in engineerng. Until now, how to calibrate bubble content is a difficulty in investigating bubbly oil. In this paper, the methods of calibrating the bubble content of bubbly oil were studied and analysed according to the author’s practice. Graduated cylinder method,pressure method and buoyancy method can be used to calibrate bubble content of bubbly oil easrily and accurately.更多还原
