heal.abstract	A numerical method was used to compute turbulent flows around U-shaped or smoothly varying bulbous bows using C-grids. The numerical method exhibited good agreement with calculated and experimental pressure coefficients. C-grids were found to be beneficial for solving flow fields around bulbs in addition to obtaining grid independency more efficiently than H-grids. The pressure resistance around full bow geometries predicted by viscous flow solvers was higher than the one predicted by potential flow. The difference may be significant at model scale but is reduced for full-scale Reynolds numbers.	en
