Various apparatuses made use of magnetic fluid, such as energy conversion systems, have been studied and developed in recent years. Accurate estimation of flow characteristics of vertical upward magnetic fluid-air two-phase flow in a small diameter tube is considered to be very important for the development. In this study, in order to find correlations applicable for the description of such characteristics, experiments have been conducted with a new test apparatus having 5 and 9 mm i.d. vertical pipes. A magnetic fluid, glycerin solution (the same viscosity as the magnetic fluid) and water were used as the test liquid while air as the test gas. In this paper, experimental results of main flow parameters, such as flow regime transition, frictional pressure drop and void fraction in two-phase flow have been presented and discussed to determine peculiar characteristics of magnetic fluid-air two-phase flow.
