Tip vortices are a major source of noise, cavitation, and hindered wake velocity recovery. In this study, we explore the mitigation of tip vortices using wing tips modified with porous treatments. Experiments and computational fluid dynamics simulation at Reynolds numbers on the order of 104 to 105 were conducted. All approaches confirmed the reduction of tip vortices. The application of porous wing tips is expected to benefit a wide range of engineering applications with wings.
