Abstract
This paper describes the deformation, breakup, displacement, and acceleration of liquid bubbles due to air streams. Experiments are conducted using a horizontal air-suction wind tunnel. The shattering processes of liquid bubbles are observed using a stroboscope. The breakup pattern of a liquid bubble varies with air stream velocity. In this experiment several breakup patterns are observed. Dimensionless time variations of dimensionless displacement, and dimensionless accelerations of liquid bubbles are investigated in detail. The dimensionless displacements are approximately proportional to the square of dimensionless time. At the initial stage, liquid bubbles have unsteady acceleration which is greater than steady acceleration.
