Paper presented at the SNAME Propeller and Shafting Symposium, September 12–13, 2023
Paper Number: SNAME-PSS-2023-013
... Model Test is a key part of the entire ship design process. The interaction between the propulsor and the hull in these tests is expressed in terms of standard coefficients and forms an important design aspect which affects the final performance of the vessel. Even though these coefficients give...

..., cavitation patterns, and load coefficients agree well with experimental measurements and observations. The results suggest that the presence of cavitation significantly modifies the boundary layer flow near the tip and the tunnel wall, disrupts the formation of the tip-leakage vortex, and enhances other...

... for performance predictions. It was found that the addition of the cup could be modeled as an increase in effective pitch. For a given KT/J2 operating curve, the cupped propeller operates at a higher advance coefficient than the original propeller when running ahead. The increase in advance coefficient leads...
