摘要
航速优化对船舶节能减排,提高能效水平具有重要意义。运用船舶动力学理论,以内河船舶为实例,规避理论模型中的不确定参数,利用实测数据确立主机油耗与航速关系模型,该模型考虑水流速度对油耗的影响,进而建立船舶EEOI与主机转速模型,并应用Matlab软件对模型进行优化求解。研究结果表明,在预定时间内,船舶主机采用优化得到的转速运行时,油耗节省0.8t,EEOI减少1.64%,提高了船舶能效水平。
Ship speed optimization plays a vital role in saving energy,reducing emission and improving the level of energy efficiency.The relationship between the EEOI and engine revolution speed is modeled by employing the ship kinetic theory,which considers the effect of flow velocity on fuel consumption.Then,the model is applied to an inland river ship and simulated by Matlab software.The result shows that the value of EEOI can be reduced effectively by 1.64%and the energy efficiency is improved by 0.8twhen the optimized revolution speed is adopted by the main engine.
