In Computational Fluid Dynamics (CFD) simulations, limited number of full-scale studies with ship propellers have been conducted due to the limitation of computational resources and computation time. There are two methods for efficient full-scale numerical analysis; (1) a method of using large non-dimensional wall-normal distances (y +) and (2) a method of applying a virtual fluid at a model scale. However, there are lack of study on the validity of using large y+ in full-scale propeller simulations and applying virtual fluids.Thus, the aim of this study is to investigate the effect of different wall y+ values in a real fluid and the virtual fluid concept to predict full-scale propeller performance using CFD. For these investigations, the commercial CFD tool, STAR-CCM+, was used to predict the propeller open water (POW) performance of the KRISO benchmark propeller (KP505) in model and full-scale. The results presented include the pressures, friction, streamlines, and tip vortex formation characteristics.The findings of this research study support the use of a small value of wall y+ (i.e., y+
