摘要：
An improved method of measuring the void fraction in two-phase mixtures has been developed. This work was part of a three-phase project that included proof-of-principle, design and fabrication, installation and probe use during a series of flow channel tests. The sensing method is based on measurement of differences in infrared transmission through liquid water as result of the presence of vapour bubbles in the optical path. The fibre optic system measures void fraction in a small volume along a line-of-sight across the flow channel. This paper covers the design and test of the fibre optic void fraction system, and application results are presented on the measurement of two-phase mixtures in flow channels.
