基于时空维度的长江主要类型船舶能耗建模及变化规律

为了研究长江主要类型船舶的能耗水平及变化规律,基于对船舶阻力及船舶通航环境的分析,从时间和空间两个维度建立长江主要类型船舶能耗模型.通过计算获得长江主要类型船舶的能耗值,分析不同船型的能耗随时间和空间两个维度的变化规律.结果 表明,干散货船的能耗总量最高;船舶上水航行时,夏季能耗最大,且在奉节至坝前航段能耗最低;船舶在...

Energy Consumption Modeling and Changing Laws of Main Types of Ships in Yangtze River Based on Time and Space Dimensions

In order to study the energy consumption level and changing laws of the main types of ships on the Yangtze River， an energy consumption model for the main types of ships in the Yangtze River from the perspective of time and space was built based on the analysis of ship resistance and ship navigation environment. Through calculations， the energy consumption values of the main types of ships on the Yangtze River were obtained， and the law of energy consumption of different ship types with time and space was analyzed. The results show that the total energy consumption of dry bulk ships is the highest. When the ship sails against the river， the energy consumption is the largest in summer， and the energy consumption in the section from Fengjie to the dam is the lowest. When the ship sails down the river， the energy consumption is the largest in winter， and the energy consumption of the Wuhan-Shanghai segment is the lowest. Among ships with deadweight tonnage less than 2000 tons， container ships have the lowest energy consumption， and among ships with deadweight tonnage greater than 2000 tons， container ships have the highest energy consumption.
