| Abstract: |
| Applying Green function method of potential flow theory,the steady moving ship hydrodynamic parameters were calculated.The Kelvin wave source Green function of steady motion in finite depth was decomposed to three parts: array of simple Rankine sources,local disturbance and wave part.Both at subcritical and supercritical speed,the singularity of integral function were eliminated by different integral path.The Kelvin source was distributed on the surface of ship by panel method,the source strength and pressure distribution on the ship surface and wave pattern were obtained.The difference and relation between finite and infinite depth results were compared.The pressure variation at bottom induced by ship was solved further.A good agreement between calculated and experiment results was found. |
