N2 - Benchmark tests of FINETM/ Marine CFD code were performed to verify the ship-resistance calculation results at high Froude numbers. The CFD code solves the Reynolds-averaged Navier-Stokes (RANS) equations with modelling of the free surface effects, that is, the generation of waves due to the ship movement on the water surface. A high-speed OSV boat was considered at three speeds (17, 20 and 26 knots), which correspond to the Froude numbers based on the volume of displacement FrV = 1.29, 1.52, and 1.98.The CFD results show a good agreement with the results of Savitsky’s formula and the numerical results obtained from Maxsurf Modeller. Further, a reasonable agreement was found between the CFD results and available experimental data. Flow visualisations show that the wave pattern behind the boat consists of transverse and divergent waves. As the boat’s speed increases, the wave height increases, and the wave pattern becomes more dominated by the divergent waves. These observations are consistent with the classical analytical predictions.
