Study on Ship Added Resistance in Regular Head Waves Based on Panel Method

摘要

Wave added resistance has great influence on the rapidity and economy of ships, and it is one of the major issues that must be considered in the design of hull lines. In this paper, a panel method based on three dimensional potential flow theory is used to study the problem of wave added resistance. The time-domain motion responses of Wigely-Ⅲ ship and S175 container ship in head waves are calculated by AQWA, and then the wave added resistances of two ships are obtained by near-field pressure integration method. By comparing the calculated results with the experimental data in literature, it is shown that the variation trend and peak value are in good agreement, and the accuracy and efficiency meet the research requirements. The present method provides an approach of satisfactory accuracy and efficiency to predict wave added resistance of ships voyaging in waves.
