## Abstract

We consider two-dimensional numerical simulation of a tandem configuration of both I-shape cylinder and circular cylinder. Diameter of circular cylinder is D as the bluff body and I-shaped cylinder has diameter of d with a cutting angle 53° as passive control, that is located in front of the bluff body. Navier Stokes equations are used to solve this problem and solved with a finite difference method. When we put the Reynolds number of R_{e} = 7 × 10^{3}, the domain distance between bluff body and passive control is a 0:6 ≤ S/D ≤ 3:0 and X/D = 2.0 then we obtain profile streamline around the bluff body, pressure distribution, separation point on the top around the 65° and on the bottom around 285°, wake and mathematics models of drag coefficient.
