However, it is widely acknowledged that the panel method can introduce significant torque errors, particularly under low advance ratio conditions. One of the contributing factors to this error is the panel method's incapacity to adequately simulate the generation of leading-edge vortices during the propeller's rotation. A leading-edge vortex correction model has been devised to alleviate the computational errors induced by the panel method, albeit without extensive validation. In this study, a comparative analysis of the results obtained from the RANS method and the panel method, corrected using the leading-edge vortex model, has been conducted. The comparison reveals a substantial resemblance in the surface pressure distribution between the two approaches. This discovery further underscores the reliability of the proposed leading-edge vortex correction model. Through computational investigations, it becomes evidently clear that this correction model effectively reduces torque calculation errors.enhttp://rightsstatements.org/vocab/InC/1.0/Panel MethodLeading-edge VortexLow Advance RatiosTorque errorNumerical SimulationEngineering and Applied OperationsConference Paper10.15480/882.930010.15480/882.9300Conference Paper
