Hydrodynamic Analysis of Ship Resistance following ITTC Method and Star CCM+

摘要

In ship design, hydrodynamics play a vital role which is conventionally solved by towing tank experiment in laboratory followed by ITTC methods for resistance calculations, causing a higher expense. But nowadays, due to development in the technological R&D, these experiments can also be performed in CFD simulation software in computers creating more financial savings by reducing the experimental setup in the laboratory. In the present study, an attempt has been taken to compare results obtained analytically from model test in the towing tank in a marine laboratory with computational results of the model obtained from simulation software, Star CCM+. It has been found that there is a fairly satisfactory similarity in the results obtained from the analytical and the computational methods practised in the present study.
