wake resistance
1.The parent form was chosen after the comprehensive analysis of 15 model resistance tests, 5 propulsion tests and 3 stern wake surveys, so it was good both from resistance and propulsion points of view.
2.Experimental Results of Resistance, Wave-pattern Measurements and Wake Survey with Series 60 Cb=0.60 Models
3.This study shows that compared with Dong 11, wavemaking resistance is decreased by more than 30%, total resistance by 0—13.2%, and propulsive efficiency is increased by 20% under the speed region of Fn=0.24-0.35. The newly designed ship consumes 22—32% less power than that of Dong 11. And the vibration of the ship is also far reduced according to the wake distribution.
