The development of a periodic boundary layer and time discretization in a sloshing flow is examined using a CFD model. The boundary layer is found to vary significantly throughout the simulation and depth of penetration is an indication for required grid resolution. Time step size is varied systematically to determine a suitable time discretization. Time step independence is determined by comparison of the sloshing
pressure history and fluid center of gravity displacement. Fluid
momentum, center of gravity displacement and impact pressure of a resonant sloshing flow are used to confirm a suitable combination of spatial and temporal resolution for sloshing impact.
