Abstract: The process of boundary layer transition is needed to be taken into account for better understanding of the flow around a hydrofoil. Based on the WALE model, this paper presents a large eddy simulation of the flow around NACA0009 blunt trailing edge hydrofoil to investigate the characteristics of the boundary layer transition at high Reynolds number. The accuracy of the WALE model in predicting the transition process is validated by comparing the calculated boundary layer velocity profiles, thicknesses and shape factors with experimental data. Moreover, the spatial development laws of velocity fluctuation in the transitional boundary layer are revealed by analyzing the profiles of resolved normal and shear Reynolds stress in both streamwise and transverse directions.
