Abstract
Green water phenomenon and the need for an effective simplified model of this problem to assist design process are introduced. Relevant models are revised and used as building blocks to develop a more efficient model. Green water experiments are described and the use of the results to derive defining parameters for the new hydrodynamic model to represent green water is explained. The model of dam-break with initial velocity is developed and simulated using CFD. Loading effects in both horizontal and vertical directions are analysed and compared with experimental results. For horizontal loading, results of the simulation of a conventional dam-break model are also included in the comparison. The comparison shows that a new model of dam-break with initial velocity is adequate to represent green water flow when investigation into green water loading effects is attempted. Improvement on the prediction of vertical deck pressure is possible if deck acceleration and its associated deck pressure component can be included.
