摘　　要：In this paper,the scale effect of Kappel tip-rake propellers with different end plate designs was studied using computational fluid dynamics.Given the base size of the mesh and the appropriate numerical model for the determined simulation,the open-water performance of three Kappel propellers with different bending degrees of the end plate at different scales was calculated.Comparing the scale effect of these propellers,the scale effect of the torque coefficient of a Kappel propeller is more intense than that of the conventional propeller.In addition,the scale effect of the torque coefficient is strong when the bending degree of the end plate increases,dwarfing the scale effect on the thrust coefficient.Following the research on the scale effect of the wake field for the Kappel propeller,the laws that reveal the influence of the scale on the wake field were summarized;that is,the high-speed zone in the wake relatively expands with the increase of the scale in company with a trend of tip cross flow.The research reveals the basic variation trend and rule of the open-water performance and wake distribution for the Kappel propeller under different scales within the Reynolds number range of 4.665×10^(5)-8.666×10^(7)consideringγtransition,as well as the characteristic differences between the Kappel propellers with different end plate designs,which will be of great significance to its optimization design and application to marine vehicles of different scales.
