Abstract

A technique based on Fresnel reflection at the tip of a fiber optic probe is used to investigate local void fractions in bubbly flows. The fiber optic system with multiplexing scheme is designed for demonstrating the feasibility of measuring local void fractions in bubbly flows. Processing the signal acquired from the fiber optic system, local void fractions can be obtained. Linear regression with least square method is applied to analyze data. The correlation coefficient of 0.94 indicates that the technique seems to be suited for measuring local void fractions in the range from 2 % to 20 %.
