Attached unsteady cavitation fluid internal structure observation device and method

The invention belongs to the technical field of ship and underwater vehicle engineering and water conservancy and hydropower engineering, and especially relates to an attached cavitation fluid experiment technology. According to the technical scheme, an attached unsteady cavitation fluid internal structure observation device comprises a water tunnel observation section, an experiment model (1), a glass window component (13), an endoscope camera (10), an endoscope lens (8), an endoscope light source (7), an endoscope lighting system (9), an endoscope image display (12) and an endoscope image acquisition and storage computer host (11). By using the endoscopic technology, an effective means is provided for observation and research of the internal complex structure of attached cavitation fluid.
