摘      要：The importance of reducing ship resistance is growing considerably as a result of the increase in atmospheric emissions and the drive towards green shipping through *** this point,Energy Saving Devices(ESD),in particular,Hull Vane®(HV),have been widely applied as a potential technique for reducing wave-making resistance for vessels with higher Froude Number(Fr).The advantages of HV for a medium-speed vessel,where the wave-making component accounts for almost 50%of total resistance,have yet to be *** study presents the computational analysis of the KCS model(1∶75.5);for a particular trim condition by using the VOF method and RANS *** hull acts as a candidate vessel for the class of medium-speed characteristics.A total of 36 numerical simulations were carried out to study the changes in resistance and motion characteristics of the vessel with and without *** validate the numerical setup,the experimental work of Hou et al(2020)on the DTMB hull was *** effectiveness of HV can be comprehended by the reduction percentage in total resistance,trim,sinkage,and transom wave height,in comparison to bare hull *** reduction in total resistance extends up to 6%for Fr=0.32 with configuration 2 with negative *** CFD results indicate that there is a reduction in trim up to 57%for the maximum speed with a corresponding Fr=0.34 with a positive angle of foil(AoF).The trim correction effect is increasing with the depth of submergence of *** sinkage,there occurs nearly a 31%reduction for Fr=0.34 with a positive *** exists a substantial reduction in the height of the transom wave with the inclusion of HV,the results of which are discussed in *** the presented results,retrofitting the Hull Vane®is effective in the selected speed range but pronouncing as the speed of the vessel increases.
