Numerical Study on the Influence of Longitudinal Position of Centre of Buoyancy on Ship Resistance Using RANSE Method

摘要

The paper presents simulation results of the influence of longitudinal position of centre of buoyancy (LCB) on ship resistance using unsteady RANSE method. First, the well-known Japan Bulk Carrier (JBC) is used to verify and validate the accuracy of CFD results of resistance with experimental data. To investigate the impact of longitudinal position of centre of buoyancy on ship resistance, five different hull shapes were generated from the initial one by using Lackenby variation method. Numerical results obtained in this study illustrate the impact of LCB position on ship resistance, especially for pressure resistance component. The solver used in this study is the commercial package Star-CCM+ from SIEMENS.
