Cavitation model tests have been carried out in the small, medium size, and in the hydrodynamics and cavitation tunnel HYKAT of HSVA. The model cavitation in the 3 tunnels for the low-skew propeller of the 'Sydney Express' and the skew-back propeller of the 'Hongkong Express' is compared with full-scale cavitation. Micro air bubbles were measured with the PDA (Phase Doppler Anemometer), and solid particles with a microscope. Their influence as nuclei on the cavitation process is addressed. The different cavitation characteristics are considered in view of the different generation of micro air bubbles, flow effects in the test sections, and other scale effects in the 3 tunnels.
