NUMERICAL SIMULATION OF SHIP WAVES IN SHALLOW WATER

Ship waves in shallow water are considerably different from those in deep water.They are greatly influenced by the depth Froude number. In the present paper, the numerical method proposed by Tanimoto et al.(1999) has been confirmed to be applicable to predict ship waves in a shallow water by comparing with experimental data by Kurata et al.(1983).Variations of the maximum wave height by the mid ship section coefficient, the distance from the sailing line and the depth Froude number are discussed together with experimental data.The maximum wave height increases as the depth Froude number increases up to the critical speed condition. In the range of super critical speed, the maximum wave height becomes almost constant or slightly decreasing tendency.
