Description

The purpose of this research is to optimize the aerodynamic performance of an airfoil with an upstream cylinder by neural network artificial intelligence. The effects of an upstream oscillating cylinder on the aerodynamic performance of an airfoil are also studied. This paper reports the effects oscillating frequency of the cylinder and the Reynolds number on the lift/drag ratio of the airfoil. The frequency has a complicated correlation with the lift/drag ratio, while the Reynolds number is found to have a positive correlation with the lift/drag ratio. The optimized case is found to have a lift/drag ratio of 1.7319, which is around 1.5 times of the reference baseline case.
