Airboat motion is always a specific maneuver operation. The flow around the airboat and the forces acting on it are quite different from those for a ship in normal act. By solving the unsteady Reynolds- Averaged Navier-Stokes (RANS) equations, the transient flow field around an airboat undergoing unsteady motion is simulated and the varying hydrodynamic force in effect of the different currents acting on the hull is evaluated in this article. OpenFoam 2.1.0 and extended toolbox will be used to do simulation. The numerical results obtained with K-omega shear stress transport turbulence models and the volume of fluid method as the suitable turbulence model are analyzed and compared with experimental results.
