We conducted computationally a parametric study to investigate the horseshoe vortex suppression due to a boundary-layer flow past a wing of finite span by a leading-edge strake. Both boundary-layer flows over a flat and curved wall were explored. In total, 48 cases were studied for various strake geometries. The Spalart-Allmaras model (1-equation model) is employed for the turbulence effect. The computational results show that different ratios lead to different flow development. Some of them can effectively suppress the horseshoe vortex. The detailed flow fields near the leading edge of the wing and the wake development are also investigated for different cases.
