Numerical simulations under seven Froude numbers are conducted in our inhouse CFD solver naoe-FOAM-SJTU. The results of total resistance coefficient and wave pattern at Fr=0.26 are used for CFD validation. The results of resistance coefficients and wave surface on ship hull under different Froude numbers are analysed, the overall results show that present numerical methods can deal with the complex flow around ship model. Comparisons of bow wave between model test and CFD at Fr=0.26, 0.35, 0.425 are given, the vorticities induced by bow wave breaking is also analysed. In order to figure out the mechanism of bow wave breaking, detail analysis of wave cuts is provided at Fr=0.35, both plunging and spilling wave-breaking are found as well as air-entertainment and splash. Present RANS model can accurately capture the overturning of bow wave but cannot deal with the unsteady capillary wave which is found in model test.enhttp://rightsstatements.org/vocab/InC/1.0/Bow wave breakingKRISO Container ShipRANS modelTechnikIngenieurwissenschaftenConference Paper10.15480/882.336310.15480/882.3363Fluiddynamik und Schiffstheorie M-8Conference Paper
