Abstract:
Void fraction as one of the basic parameters of gas-liquid two-phase flow is of great significance to the development and transportation of petroleum pipelines and the design of nuclear reactor cooling towers. Thispaper proposes a void fraction detection method based on PIV technology, which can obtain the velocity distribution and void fraction of the cross-section at the same time. During the experiment, the truth-value of void fraction of the cross section is obtained by installing an endoscopic camera at the back of the test section. The deviation of the void fraction obtained by the two detection techniques is calculated and corrected, and the maximum deviation is only 0.0246. The results show that the method proposed is effective for measuring the void fraction of gas-liquid two-phase stratified flow.
