Calculating pressure distribution on water bottom caused by a moving ship with panel method

LI Kun,ZHANG Zhi-hong,GU Jian-nong,MIAO Tao(College of Science,Naval Univ.of Engineering,Wuhan 430033,China)  
The research on the hydrodynamic pressure field of a ship is the foundation of designing a new pressure mine,developing a minesweeper and protecting the ship,which is of great military significance.A mathematical model for the ship hydrodynamic pressure field was established based on the marine hydrodynamic potential flow theory.The sources were distributed on the ship hull surface by using the Hess-Smith method.The pressure caused by the ship at the limited water depth was calculated and compared with the experimental results.The characters of the ship hydrodynamic pressure field and the effect of water depth and the ship hull shapes on the pressure field were analyzed.The comparison shows that a good agreement is achieved between the theoretical calculation results and the experimental ones.
