Abstract
This experimental research concerns an air-bubble-jet flow in water. We apply a three-dimensional particle-tracking-velocimetry (3D-PTV) technique to the flow, in order to obtain both air-bubble and ambient-liquid (water) velocities. In bubble-velocity measurements, we regard air bubbles as tracers. And, in liquid-velocity measurements, we regard polyethylene particles suspended in the liquid as tracers. Then, we visualise the three-dimensional motions of air bubbles and ambient liquid. As we record stereo images using two high-speed video cameras, we can get timely-consecutive information of air-bubble and ambient-liquid motions. As a result, we quantitatively reveal the three-dimensional unsteady flow of a simple bubble-jet plume near an air nozzle exit.
