4 CONCLUSIONS

Utilizing our method, the FINFLO-RANS code with a moving mesh, the overall degree of accuracy
has been achieved for simulation of a turbulent free-surface flow around a modem ship. This has be
demonstrated with the benchmarks: the KCS model, the DTMB 541 5 model, the tanker model and the
HTC model. using the B-L model and the k-E model, respectively. They are in very good agreement
with the experimental data available. It is believed that the present study can provide the detailed and
extensive information for analysis and design of ship.
