In this work, the propulsive characteristic of an auto-propelled 2D NACA0015 foil undergoing traveling wave motion is numerically investigated. The effects of typical motion parameters, i.e. traveling amplitude, traveling frequency (f), and geometric parameters (thickness, d) on the propulsive property of auto-propelled foil are systematically investigated. The numerical results reveal that the moving velocity of foil can be significantly enhanced by the enlargement of the traveling amplitude and traveling frequency, while it presents a sharp decrease when the foil thickness increases. As for the propulsive efficiency, the effects of a 1, f and d on the magnitude of η are similar to each other, that is, the magnitude of η will ascend to the peak value and then decrease, and there exists an optimum value corresponding to the highest magnitude of η. The flow structures in the wake of the auto-propelled foil under typical calculation conditions are also analysed.
