In this research, we focused on simulating the flow of water around I4.000-TEU

container ship hull in according toRASSE approach (Reynolds-Averaged NavierSlokes

equation). On that basis, we calculated the hydrodynamic forces exerting on the hull when

making uniform motionin still water: then compared between tlieCFD simulation calculation

results with the experimental results in the testing reserx'oir have been aniwunced. The flow i\

considered turbulent, and described by the equation R.-i \S (Reynolds-Averaged \avierStokes).

SST turbulence model k-w.
