Numerical simulations were carried out for two different vessel models, one with an optimized bulbous bow and the other without a bulbous bow, by solving the Reynolds-Averaged Navier-Stokes (RANS) equations. The numerical solutions were validated against the experimental results. The wave profile along the ship hull and wave elevations on the free surface are presented. The effect of grid resolution on predicted total resistances for the two models was investigated. Uncertainty analysis based on the Least Square Root (LSR) method was carried out to evaluate the accuracy and reliability of the numerical results.
