Abstract

Abstract

In order to study the two-phase distribution in the rod bundle channel, a wire mesh sensor module suitable for the rod bundle channel was designed and fabricated, and the experiment of measuring the void distribution of air-bubble flow in a 5×5 rod bundle channel was carried out. The distribution law of void fraction in rod bundle channel and the effect of bubble size on void distribution are analyzed. The experimental results show that the small bubbles with reversal of transverse lift direction gather near the wall, and the large bubbles gather in the center of the subchannel; The critical bubble diameter of transverse lift direction reversal at room temperature and pressure is between 4~6 mm, which proves the applicability of transverse lift model in rod bundle channel.
