Numerical simulation for the free surface flow around a complex ship hull form at different Froude numbers

Abstract

The incompressible turbulent free surface flow around the complex hull form of the DTMB 5415 model at two different speeds has been numerically simulated using the RANSE code CFX. The Volume of Fluid method (VOF) has been used with CFX for capturing the free surface flow around the ship model at the two speeds. The simulation conditions are the ones for which experimental and numerical results exist. The standard k–ɛ turbulence model has been used in CFX code. The grid generator ICEM CFD has been used for building the hybrid grid for the RANSE code solver. The results compare well with the available experimental and numerical data.
