Research on the Calculation Method of Pressure Field Caused by the Ship Moving at Subcritical Speed in Shallow Water

  • 摘要: 基于浅水波动势流理论和薄船假定,建立了浅水亚临界航速舰船水压场理论数学模型.采用有限差分方法,对浅水亚临界航速舰船水压场分布特征进行了数值计算.分析了航道岸壁、Froude数、色散效应对舰船水压场的影响,利用虚拟长度法改善了计算结果.通过与源汇分布法、Fourier积分变换法以及实验结果进行比对,验证了所建立的舰船水压场数学模型和计算方法的正确性.
