摘要：
A real-time two-dimensional void fraction distribution measurement of gas-liquid two-phase Row was carried out by real-time neutron radiography and real-time image processing. The JRR-3M real-time thermal neutron radiography system and a Musashi dynamic image of processing system were used. Image processing methods to calculate two-dimensional and cross-sectional void fraction distributions were proposed. The void fraction distribution was calculated by non-linear processing of the neutron radiography image and displayed by pseud-color in real-time. A simple gas-liquid two-phase Bow induced by injecting gas through needles at the bottom of water pool in a rectangular vessel was tested.
