Abstract

This paper focuses on the effects of the changes in the resistance characteristics caused by the changes of the POD shape installed in the Hydrofoil vessel, using the CFD(Computational Fluid Dynamics). We input the POD sections' basic shape as the origin of the x and y axis. Then as we cut the x-axis 0 to 2 cm, and the more we cut it, the total resistance value had increased. However, we have recognized the fact that as we cut the POD section, 3 to 5 cm, the resistance value had rather decreased. Furthermore we found out the result that as the cut partition was larger; the POD cross-section would decrease, resulting in the linear decrease of the viscous force.
