LARGE-AMPLITUDE SLOSHING IN AN OIL TANKER WITH BAFFLE-PLATE DRILLED HOLES

The sloshing dynamics in a tank partially filled with liquid oil was s imulated in this study. The formulation uses primitive variables on a staggered grid system for solving incompressible Navier-Stokes equatio ns, which are subjected to the distortion of free surface. We made use of a volume of fluid technique to resolve numerical difficulties in a ssociation with nonlinear free-surface boundary conditions while a two -dimensional quadratic upwind advection scheme to deal with flux nonli nearities, Two problems, namely the free oscillation and the solitary wave propagation, have been chosen for benchmarking the method present ed here. The liquid oscillations under conditions of resonance or nonr esonance frequency in an oil tanker containing a perforated baffle pla te have been studied extensively for two different liquid levels. Thro ugh this simulation, we have found that the degree of sloshing can be mitigated by these baffle plates.
