KAKENHI (Grants-in-Aid for Scientific Research) 1

  1. Study on the generation and transport of bubble cluster by a vortex ring

    A study searching for the generation and transport of a bubble cluster by a vortex ring is carried out. A vortex ring is launched vertically upward into a water tank by discharging the water from a cylinder mounted at the bottom of the tank with a piston. Air bubbles are injected into the vortex ring from a needle attached to the cylinder outlet. The cylinder inner diameter and the piston stroke are 42.5 mm and 100 mm, respectively. The mean diameter of the bubbles is 3.4 mm. When the strength of the vortex ring is large than a critical value, the bubbles are entrained in the vortex core and form a cluster. The entrained bubbles are successfully transported by the convection of the vortex ring. The convection velocity of the vortex ring is scarcely affected by the entrained bubbles, but the radius is enlarged slightly.
