This paper describes a new measuring technique of void fraction using a magnetic fluid. The proposed measurement utilizes the electromagnetic induction so that the measurement can be realized with simple experimental devices. The present study consists of two kinds of experiments; one is “static experiment (calibration test)” and another is “flow experiment (actual flow test)”. In the present study, the experiments have been performed with fully diluted magnetic fluid for the purpose of applying to the ordinary two-phase flows such as water-air two-phase flow. Results of the experiments have verified that the proposed measuring technique of void fraction is very effective to measure the void fraction in the two-phase flow by adding a small amount of the magnetic fluid to objective fluid.
