Numerical Investigation of Validation and Verification for the Resistance of JBC Hull

Abstract

Regarding the purpose of determining the hydrodynamic properties of ships, the potential uses of computational fluid dynamics (CFD) have been performing significant progress. The prediction of resistance is one of the several task that is considered to be among the most essential components when designing a ship. The present study involves conducting numerical simulations in STAR-CCM+ to determine the resistance and resistance coefficient produced by the Japan Bulk Carrier (JBC) hull in calm water condition. There is also an investigation into the verification and validation processes that are carried out using three distinct grids that have been precisely refined. The numerical findings of the study that are very similar to the experimental findings arising from the towing tank model evaluation. Through current numerical approaches and grid distribution are capable of effectively predicting fluid flow region that is sufficient to encompass JBC hull since wave patterns provide an accurate representation of Kelvin wave patterns. In addition, the uncertainty of the comparison is lower than the uncertainty of the validation which implies that the validation has been effectively achieved.
