In this work, effects of manufacturing defects on the cavitation performance of a propeller blade section were studied with 2-D steady RANS solvers. DTMB modified NACA66 a = 0.8 sections without and with leading edge (LE) defects were investigated at various angles of attack using Star-CCM+ on structured grids. Using the best-practice settings, verification studies were carried out for the cavitation buckets of a 20% thick 2% camber section without a defect. The main body of this work examines minimum pressure coefficients on a 4.16% thick 1.4% camber section with and without defects near the LE. These lead to conclusions about the relative cavitation inception speeds of defective sections and the consequences for manufacturing tolerances.
