Research of the Three-Dimensional Airfoil Wake

This study focuses on how to locate the wake position of a three-dimensional airfoil due to a uniform flow. Based on the potential theory, the boundary integral method is applied to solve the velocity potential on the boundary of the airfoil. Once the strength of the velocity potential is solved, it can be substituted into the boundary integral equation and find all the velocity potential in the flow field. By adjusting the shape of the wake, and minimizing the normal velocity components on the surface of the wake, the goal is to select a correct position of wake.
