The thickness manufacturing defects were distributed between the blade sections of r/R = 0.5 and r/R = 0.9. Three thickness deviations (0.5%, 1.0% and 2.0%) within ISO 484 Class S between 0.4c and 0.5c along the chord length were applied. Following the recommended best-practice settings for RANS simulations in previous studies on leading-edge (LE) defects, open-water simulations were conducted for full-scale propellers with and without thickness defects. The results indicated that maximum reduction in cavitation inception speed due to thickness manufacturing tolerances reached 7.48% for the investigated advance ratios.enhttp://rightsstatements.org/vocab/InC/1.0/RANSthickness manufacturing tolerancescavitation performanceDTMB 5168 propellerEngineering and Applied OperationsConference Paper10.15480/882.930310.15480/882.930310.15480/882.9294Conference Paper
