To enhance the accuracy of predicting cavitation around a hydrofoil, we conducted a large eddy simulation using a 2-D hydrofoil model. Our focus was on assessing the precision of prediction through analyses of both non-cavitation and cavitation flows around the Clark-Y hydrofoil. We explored different grid resolutions in computational cases to understand their impact on the results. Opting for the highest grid resolution, we aimed to accurately capture the turbulent boundary layer near the wall. Our discussions centered on friction and pressure coefficients, revealing the influence of grid resolution on these parameters. In the non-cavitation case, the simulation conditions and grid resolution used in our study produced results consistent with previous experiments. Additionally, the cavitation results implied a correlation between grid resolution and cavitation length, with lower resolutions resulting in longer cavitation lengths.
