Description/Abstract

As part of the ISOPE 2009 sloshing comparative study, the eight
specified test problems are analyzed using the CFD code CFX-11. The computational models and meshes are based on the methods developed in previous studies. 20 oscillations are simulated for each case and the mean, maximum and the mean of the 1/10th highest pressures are computed for each specified pressure sensor. The flow features and their influence on the impact pressure magnitude are then considered and both hydrodynamic impacts and impacts with air entrapment are
observed. It is found that the peak pressures are up to 170 kN/m², with time durations of the order of one millisecond. The resolution of such small time scales and the occurrence of wave breaking and air entrapment, which influence the pressure significantly, require a robust multiphase model capable of simulating phase mixing.
