The effect of porous lamination on zero pressure gradient flow over a flat plate is analysed using experiments from a separation control perspective. The porous lamination is modeled as an array of cylinders placed downstream of a backward facing step. The porosity of the lamination, φ, is calculated using the distance between the cylinders and values of φ= 0.65 and 0.8 are studied at Re= 391, 497 and 803, based on the characteristic length of the porous lamination and the free stream velocity in the wind tunnel. The temporal (·) and Representative Elementary Volume averaged (〈·〉) values of the flow properties are compared with those for the flat plate boundary layer flow to comprehend the influence of the porous layer. The flow dynamics at the fluid-porous interface is investigated with focus on the interfacial slip velocity, Uslip, and its dependence on φ and Re. The velocity measurements confirmed the existence of a non-zero slip velocity at the fluid-porous interface, by virtue of the porous lamination.〈 Uslip〉 was found to increase with φ and Re. A passive suction-blowing velocity was also observed at the fluid-porous interface at higher φ and Re, which resulted in flatter velocity profiles over the porous lamination. Numerical analysis is carried out to analyse the φ and Re outside the scope of the experimental investigation and provided necessary data to substantiate the experimental analysis. The presence of the slip wall and the flatter velocity profiles suggest a stabilization of the flow and indicate separation delay. Hence, we propose the use of porous lamination as a passive separation control strategy.
