抄録

This experimental research concerns the air-bubble-jet flow in water. We try to apply three-dimensional particle tracking velocimetry to the flow. Air bubbles are regarded as tracer particles. Then, we visualise the three-dimensional motions of the bubbles. As we record the stereo images using two high-speed video cameras, we can get timely-consecutive information of the bubbles' motions. As a result, the three-dimensional structures of two simple bubble-jet plumes with different nozzle's tilting angles have been quantitatively revealed near the nozzle exit.
