Abstract

In this paper, an integrated computational procedure for the simulation of a two-phase flow, as well as floating and submerged body motions, is presented, based on a Volume of Fluid (VoF) - fractional step coupling. Two fluids are modeled as a single continuum, with a fluid property jump at the interface, by solving a scalar transport equation for the volume fraction. In addition, the conservation equations for mass and momentum. Are solved using the fractional step method. Based on the integration of stresses over a body, acting forces and moments are calculated. The strategy of non-orthogonal body-attached mesh and calculation of the motions at each time step, result in the time history of floating or submerged body motions. The motion simulation strategy is evaluated by using a cylinder water entry test case. To demonstrate the capability of the simulation, barge resistance is also calculated in two cases of fixed and free motion (2-DoF).All of the results are in good concordance with experimental data. and the present method can be extended for the full nonlinear-motion of ships in waves.
