Wave resistance determination by pressure integration and wave cut analysis using non-linear rankine panel method

ABSTRACT

This study explored the numerical method to calculate wave-making resistance. The fully non-linear Rankine source method was implemented in a computer program in this paper. Using the results from the Rankine source method, the wave resistance was calculated by the direct pressure integral and the multiple transverse wave cut analysis. The wave resistance of the Wigley and Series 60 ($C_b$=0.6,0.7,0.8) hulls were calculated using both methods and compared against the experimental data. Results obtained through a combination of the Rankine source method and the wave cut analysis appears this combination is an effective way to calculate the wave-making resistance, especially for full-form hulls at high Froude numbers.
