Concepts in submarine shape design

Abstract

100-104This paper uses CFD method for analysis of six different models of submarines. The resistance coefficients of each shape are presented and compared so that could understand the reason of submarine shape selection with tapered stern and curved bow. Focus of this paper is on the cylindrical middle body submarine such as the most of naval submarines and ROVs. Determination of diameter and length of submarine is related to the L/D ratio that is somewhat discussed here by CFD modeling. The tools of CFD modeling is Flow Vision (v.2.3) software that is known as a skilled software in CFD modeling
