Numerical simulation was conducted for fluid flow past a circular cylinder with triangular control rod in the upstream at low Reynolds numbers. The study focuses on the influences of leg length of rod L, rod-to-cylinder spacing ratio S, vertex angle of triangular α of rod on the vortex shedding and forces. The results show the equilateral triangle rod in the upstream takes effective suppression of not only the lift but also the drag in the range of 0.2R≤L≤0.5R and 3R≤S≤6R(R is the radius of circular cylinder), and the vortex shedding between the two cylinders maybe lead to sharp increasing of the force on the circular cylinder.
