College of Science, Naval University of Engineering, Wuhan 430033, P.R.China

摘要

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．

Abstract: A mathematical model for pressure field caused by the ship moving at subcritical speed in shallow water was established, based on the shallow water wave potential flow theory and slender ship assumption. The pressure field caused by the ship moving at subcritical speed in shallow water was calculated by the finite difference method.The effects of channel wall, depth Froude number and dispersion characteristics on the ship hydrodynamic pressure field were analyzed.The calculation results were improved by the virtual length method.The computed results were compared with the ones calculated by source distribution method,Fourier integral transform method and experimental results. The mathematical model and the calculation method were validated.
