2134 回転二重円筒による気泡流の実効粘性の計測  [in Japanese] Measurement of Effective viscosity in bubbly flow using Rotating Coaxial Cylinders  [in Japanese]

Effective viscosity of liquid containing bubbles is experimentally investigated by means of the rotating coaxial cylinder method. The rotating coaxial cylinder method measures the relative viscosity of the two-phase fluid to the single-phase fluid from the torque for the inner cylinder by a torque meter. In this research, it is made clear that the viscosity characteristics of spherical bubble mixture. The measurement results show that the effective viscosity has a peak on the relationship with shear rate.
