Abstract

To investigate the movement of each bubble individually, we attempt a 3D PTV analysis of air bubbles. A compressor blows air into water in a 1m×1m×1m cubic tank through a converging nozzle with an inner diameter of 0.3[mm]. The pressure p 0 of a chamber between the compressor and the nozzle is 1.0×10⁵, 2.0×10⁵ or 0.1×10⁵ [Pa]. We take the stereo pictures, using two high-speed cameras. Choked and non-choked conditions are compared.
