Abstract

As designers aim to increase the aerodynamic efficiency, fractal spoiler may be used on wings for its ability of altering turbulence. The study focuses on analyzing and verifying the feasibility of applying fractal spoilers. The flow mechanism of the flow-through fractal grids is simulated using CFD methods. Both the laminar and turbulent conditions are considered when simulating. The simulation of the wing airfoil provides the velocity distribution to the fractal spoiler. The laminar results help us understand the flow mechanism including wakes, jets, and their interaction behind the grids. In the turbulent results, the importance of the parameter wake interaction length is stated, and compared with former papers. The parameters of the fractal grids are related to a number of flow properties including the turbulence intensity, homogeneity, isotropy, and velocity distribution. These special characteristics suggest that it’s feasible to use fractal spoiler on wings as a control method.
