MEASUREMENT OF THE VOID FRACTION IN UPWARD GAS/WTAER TWO-PHASE FLOW IN
VERTICAL TUBE[J]. Thermal power generation, 1999, (3). DOI: 10.19666/j.rlfd.1999.03.002.
Abstract The void fraction in upward gas/water two-phase flow in vertical tube is measured by the combined method of horizontal-upward vertical tube for the two flow regimes
bubbly and slug flow.At the same time
a theoretical model is used to predict the experimental results and a good agreement between the experimental and the predicted results was obtained.It is proven that the combined method is a simple
accurate and convenient measure tool in the engineering applications.
