Research on Ship Resistance Performance in Restricted Channel of Wujiang River
Taking Wujiang Waterway as an example,the resistance and self-propelled performance pa-rameters in different water depths were tested based on the model resistance and self-propelled test of the thousand-ton green and energy-efficient standard ship type currently popularized and applied.The Froude transformation algorithm was used to estimate the resistance and effective power of the real ship,and the corresponding law between effective power and speed under various working conditions was analyzed to select the appropriate main engine power for the standard ship type.Based on the cur-rent situation of ship energy application,different power schemes were formulated,and the corre-sponding carbon emissions and necessary freight rates of each scheme were calculated and compared,and finally the diesel-natural gas dual-fuel power mode was recommended.
