چکیده:

In this paper, a 2D numerical model is developed for simulating the interaction between waves and floating body. The fluid flow is assumed to be viscous and incompressible and therefore, Navier–Stokes and continuity equations are used as governing equations. The fastfictitious- domain method is used into the volume-of-fluid (VOF) technique for tracking the free surface and storage tank motion. The Navier–Stokes equations are discretized usingstaggered grids finite difference method and solved by SMAC approach. Some standard tests such as lid-driven cavity and constant unidirectional velocity field are performed to valid the model. Finally, floating storage tank motion due to waves is simulated using fictitious domain method. The results show that the maximum vertical floating body motion is increased by about 150% if the wave amplitude is doubled
