This paper investigates a new method to eliminate the Horse-Shoe Vortex (HSV). It involves creating a thorough hole at the base of the cylinder where the HSV is formed. CFD simulation was conducted using ANSYS 15.2, and the results were compared and analyzed with and without the presence of the hole. Different speeds of the upstream flow without the hole and different hole heights were investigated. The minimum effective height that eliminated completely the HSV was determined. The qualitative analysis of CFD results showed that the HSV was eliminated totally at certain ranges of the dimensions of the hole.
