Flow control techniques are broadly classified into two types 1.passive control 2.active control. Present paper discuss about the experimental investigation of flow control using passive method on bluff body. Authors also explains about the various flow control techniques used in bluff body aerodynamics. Experimental setup consists of L m span and diameter d of cylinder model. The next model is having strip of cross section 0.01d dia is placed on the cylinder along the span wise distance with equal polar distance around 30o. both the models were kept between four walls in a Reynolds number ranging from 10000 to 15000. The results show that the Cp values changes according to the changes in cylinder roughness.
