The objective of the proposed research is to carry out numerical and experimental studies on the performance degradation of propeller blades in three different scales with leading-edge (LE) manufacturing tolerances. In the experimental studies, three single propeller blades in three scales (1:1, 1:2 and 3:4) will be tested in a cavitation tunnel. Flow velocities and […]

The objective of the proposed research is to investigate the performance degradation of a full-scale modified NACA 66 section, which is typically used for marine propellers, due to leading-edge (LE) manufacturing tolerances. Two-dimensional computational fluid dynamics (CFD) simulations will be carried out for the base section without defect (as designed) and sections with LE defects […]
