Abstract
The Naval Surface Warfare Center Carderock Division (NSWCCD) Model 5365 (R/V Athena) was chosen to facilitate the detailed comparison of experiments and simulations of a semi-planing hull in calm water and waves. This paper focuses on the comparison of the calm water experimental results from three different tests with four simulation predictions from two computational codes. The comparisons show differences with the same order of magnitude as comparisons of experimental and simulation with large displacement vessels. The MxN-order level analysis has shown that the scatter in the data between the three experiments dominates the experimental uncertainty in the semi-planing regime. The N-Version analysis of the four simulations shows that the scatter in results for both the experiments and the simulations drives the state-of-the-art uncertainty. The resistance, trim, and sinkage was validated at a variety of speeds for individual codes and the simulation mean. This study has shown the importance of experimental setup and the initial conditions of numerical simulations when comparing experimental and numerical simulation results. The errors due to the hydrostatic setup and the transom radius proved to be a contributor to the error between the experiments and simulations.
•Experimental data set of semi-planing hull in calm water collected for validation.•Favorable comparison of multiple simulations with experimental data set.•Similar accuracy for prediction of semi-planing hulls, as for displacement hulls.•Setup and initial conditions important for validation of semi-planing hulls.
