Abstract
AbstractThe main purpose of this research is to investigate and improve the method of solution by the final root method on ship wave resistance due to variation of block coefficient and angle of entrance of different ship hulls. The method of solution and the calculated results are validated by comparing against the experimental results. The results obtained by the proposed hypothesis would be used in predicting the ship wave resistance and the overall powering estimation of any ship. This was done by developing functions of block coefficient and angle of entrance versus Froude number. Standard series-60 experimental data were used in the study to develop the relationships between the ship wave resistance versus block coefficient and angle of entrance. Corrections to the calculated ship wave resistance coefficient were achieved by using a structured regression method applied to the ships under study. A significant improvement of more than 1% on the ship wave resistance was achieved.KeywordsBlock coefficientAngle of entranceSeries-60
