Abstract

Aiming at the problem that the low average flow velocity in most sea areas of China leads to insufficient applicability of hydraulic turbines, the airfoil design before and after optimization by surrogate model is optimized in two and three dimensions at low flow velocity. Based on the Rukowski theorem, the model of low velocity tidal current energy airfoil is designed, and the original airfoil with relative thickness of 12% and relative camber of 2.5% is obtained. The 4th-order CST equation is set in the proxy model to optimize the parameters. The results show that the airfoil with thinner thickness and larger camber has better hydrodynamic performance. After optimization, the maximum thickness point moves forward by 4.58%, and the lift-drag ratio increases by 4.03%, so the blade power is more stable and excellent, which provides new ideas for the research of airfoil design of hydraulic turbine impeller at low flow velocity.
