Evaluation of Added Mass for an Underwater Vehicle Using Boundary Element Method

In this paper, added mass coefficients of an underwater vehicle were calculate using boundary element method. Fluid flow was solve using boundary element method on triangular meshes created by GAMBIT. For verification purposes, added mass coefficient of typical ellipsoid and sphere in various aspect ratios were considerd. The results for typical ellipsoid and sphere were compared with analytical results. As an applicable research, Suboff submarine was investigated. Added mass coefficients of Suboff submarine which was determine by boundary element method was compare with experimental results then. The results show good consistency in comparison with experimental one.
