When a single-slotted circular cylinder with tangential blowing is installed downstream of the main jet, the deflection characteristics of the main jet depend on the position of the circular cylinder. However, there are few reports on the application of multiple-slotted circular cylinders with tangential blowing for the main jet vectoring. In this study, the flow around a double-slotted circular cylinder installed downstream of the main jet was experimentally investigated. The visualization results of the flow field around the circular cylinder of the single and double slots were compared. Specifically, the relationship between the deflection angle of the main jet and the installation position of the circular cylinder was considered. It was found that the deflection angle of the main jet depends considerably on the installation position in the single-slotted circular cylinder, whereas its dependence on the installation position is not significant in the double-slotted circular cylinder.
