摘要
本文提出以六重模速度势线化自由面条件解浅水船波问题的方法。作为算例,对Wigley船型进行了实际计算。根据计算结果,讨论了浅水对波形及兴波阻力的影响,给出了浅水影响起始傅氏数、临界傅氏数与水深关系曲线。结果表明,所给水动特性与实验结果吻合,本文方法能较好地对浅水船波问题进行数值模拟。
In this paper a numerical method is proposed for sioving ship-wave problems in shallow water. The free surface conditions are linearized in terms of the sixfold-model velocity potential. The numerical results are given for Wigley model 1850A. Based on the results, the effects of shallow water on the wavemaking resistance and the wave profile are discussed. The curves of the initial Froude number corresponding to the effect of shallow water and of the critical Froude number are plotted against water depths. The results show quite good agreement between the calculation and the experiments [4] [5]. The method can be used to simulate numerically the ship-wave problems in shallow water.
