There are many ways to reduce the drag force of an object, one of them by adding another smaller object called the passive control. Two passive controls will be placed in front and rear of the main object. The main object is a circular cylinder, the passive control that is in front is the cylinder type-I and the rear is an elliptical or circular cylinder. The distance between the main object with the two passive controls is varied and the Reynolds number used is 1000 and 5000. We want to find the effective distance of the main object with both passive controls so that the drag coefficient of the main object is minimal compared to the non-passive control or with one passive control in front of.
