• 論文の詳細を見る

• Experiments have been conducted for turbulent liquid plane Couette flow with an immiscible droplet in order to understand interfacial deformation and the modification of the structure of shear-dominant turbulence due to immiscible droplets in turbulent dispersed liquid-liquid two-phase flows. Flow visualisation, an image-capturing method and image processing have been used for the measurement of the fluctuating velocity field. Mean velocity, turbulence intensities, turbulent kinetic energy and mean vorticity have been estimated from the velocity field. The present work clarifies that the turbulence energy and the vorticity increase at the confluence of the axial flow and the flow along the interface in the direction perpendicular to the moving wall, and that they decrease in the stagnation region of the main flow near the interface.
