CFD Optimisation of the Longitudinal Volume Distribution of a Ship’s Hull by Constrained Transformation of the Sectional Area Curve

Abstract The paper presents a proposal for formalised approach to hull shape optimisation with respect total resistance, by fine-tuning longitudinal volume distribution. An algorithm automated modification of the is presented, allowing varying sectional area distribution negligible influence on resulting displacement. Computational fluid dynamics (CFD) solver STAR-CCM+ and computer computer-aided design (CAD) software NX were used search optimal selected parent shapes, resistance. bow part aft optimised separately. resistances shapes then verified means scale model tests, realised in towing tank at Maritime Advanced Research Centre (CTO) S.A. A noticeable gain resistance was achieved confirmed experimental tests. proposed seems be promising method relatively quick parametric designed shapes; it also applicable generic CFD studies.
