Based on hydraulic machinery blades airfoil design, numerical simulation was carried out for the hydrodynamics force of airfoil with different camber at Re = 10 7 . Firstly, the numerical simulation of airfoil was performed with structured grid and the Reynolds-averaged Navier-stokes-method, which coupled with the k – ε turbulence model. Secondly, the drag and lift characteristics of airfoil with different camber were analysed. Finally, the flow field and pressure distribution of the airfoil was discussed. The result shows that as camber increases, drag, lift and lift-to-drag ratio increase, while the attack angle corresponding to maximum lift-to-drag ratio decreases. The results are useful for understanding the hydrodynamic performance of the airfoil, and provide an important theoretical basis for the design, selection and development of the airfoil in hydraulic machine.
