Note (General): The flow characteristics of an immiscible equal-density liquid two-phase mixture were investigated to clarify the behavior of a gas-liquid two-phase flow under microgravity. The experiments were carried out in a horizontal transparent acrylic resin tube of 4.5m in length and 25mm I.D.,using silicone oil(viscosity µo=55.0mPa・s,density ρ=980kg/〓)and water mixture as the working fluid in the range of superficial oil velocities of 0.03 to 0.40m/s and superficial water velocities of 0.001 7 to 0.7m/s. Seven kinds of flow patterns were observed. In particular,the inverted annular flow and the inverted slug flow occurred. In these flow patterns the water touched the tube wall and the oil flowed in a core region. The mean void fraction was clarified using the drift flux model. Furthermore,the experimental results of the frictional loss were compared with the Lockhart-Martinelli correlation. As a result,it was found that both agreed well in bubby,slug,and annular flow regimes when the oil touched the tube wall,but neither agreed in the inverted flow patterns when the water touched the wall.
