Fluid flow has the potential to provide significant mechanical energy input for electromagnetic energy harvesters. The effect of a bluff body, such as cylinder played a significant role in the creation of a Karman vortex profile in the fluid flow. We study the effect of the number and position of the Duffy cylinder on the characteristic of the aerodynamic system of the elastic belt such as the lifting force. In such a configuration, a flutter energy conversion device (FECD), which could be placed in turbulent boundary layers, can work as an energy harvester. In this work, we focus on the interference between flow disturbing conditions by using three cylindrical bluff bodies in three configurations.
