摘要: Abstract:It is the design goal for marine propellers to deliver highly efficient performances while remaining free of cavitation. To examine the performance of a propeller, its down-sized, physical model is usually used for the test in a well-controlled laboratory environment. Therefore, the test result shall be governed by some unknown scaling law and cannot truly reflect the full-scale situation. This fact also serves as the reason why the imaging of full-scale cavitation is receiving more and more attentions. This paper first examines previous cases of full-scale cavitation imaging in open literatures, resulting in a list of key items for the system development that includes the position choices and the design of imaging windows, and the construction of lighting and imaging system. In the development process, we analyze and design imaging windows to meet the structural strength requirements under static and dynamic loadings, design a focusing cover cap installed in front of a LED light source to improve its luminance, and test an industrial camera whose focal length, shutter speed, and aperture are remotely-controllable for building the major block of the imaging system. Finally, the under-water imaging scenario is simulated in a water tank and the results reasonably verify the suitability of the system.
