垂直上升管内气水两相流动截面含气率的测量

The Measurement of Void Fraction of a Two phase Flow in Vertical Riser Tubes

用水平－上升管组合法测量垂直上升管内气水两相流动在泡状流和弹状流情况下截面含气率的值，应用理论模型对实验结果进行了预测，预测值与实验结果吻合良好。证实了此方法在工程应用中是一种简单、准确、可行的测量方法。

The void fraction of gas water two phase flow in a vertical riser tube under bubble and slug flow conditions is measured by the use of a combination horizontal riser tube method.The experimental test results are forecast using a theoretical model.The forecast values agree well with those of experimental results.This proves that the above mentioned measurement method is a simple,accurate and feasible one.
