The Computational Fluid Dynamic simulation proposed approach is aimed to attain this precise outcome, while a hydrodynamic description of the rationale underlying behind the results is explained. Several effects of lateral separation ratios (S/L) and longitudinal staggered position (R/L) against a wide range of Froude numbers (Fr) from 0.5 to 1.0 were considered. The results revealed that the general increase in Fr is proportional to the increase of total resistance. In contrast, the increase of lateral separation ratios dealt with less total resistance coefficient, where the sufficient reduction of CT was about 11% as the Fr increase from 0.5 to 0.6 for S/L=0.3. Regardless of R/L ratios, the results showed the subsequent increase of Fr from 0.5 to 1.0 was also proportional to the total resistance, where the maximum increase of RT was about 21% as the Fr increase from 0.6 to 0.7. In addition, the increase of R/L ratios has led to sufficient increment of CT by 1.5% as the Fr increase from 0.9 to 1.0. Generally, the increase of S/L and R/L ratios have similar effects on the total resistance characteristics. This CFD simulation results are very useful as preliminary data for the ship resistance, which is mainly required for predicting a ship powering accurately.</p>}, number={2}, journal={International Journal of Automotive and Mechanical Engineering}, author={Fitriadhy, A. and Azmi, S.
