The flow around a sphere falling through viscoelastic wormlike micelle solutions is investigated by using a particle image velocimetry (PIV) when the falling velocity of the sphere is high compared to the shear wave speed of the fluid. The speed o...

PIV measurements were conducted for the development of the withdrawal current of viscoelastic fluid induced by a line sink between parallel walls. The experiments were performed in a rectangular reservoir 700 mm long, 50 mm wide, and filled with a...
Particle image velocimetry (PFV) based on an optical flow equation requires numerical evaluation of temporal differential terms between two particle images, which has an unmanageable source of noises. In this research, by using a generally availab...
In this study, we focus on substance transportation of counter-rotating vortex-pair in the uniform flow, and its interaction with a flat plate is visualized. A water tunnel and aluminum wings (NACA0012) are used to generate a wing-tip vortex pair....
