Abstract [en]

In this paper Large Eddy Simulations are used to study the reduction of drag that can be achieved on a half-submerged cylinder by using a type of plasma actuator: the single dielectric barrier discharge. Two body force models, one based on an exponential decrease of the force away from the plasma, the other based on a simplified electric field between the electrodes, are compared to experimental values when the actuator is positioned at the apex of the cylinder in an otherwise quiescent environment. The cylinder is then put in a crossflow, and the exponential-based model, which gives the velocity profiles the closest to the experimental data, is used to simulate the effect of the plasma actuator on such a flow. The reduction in drag is changed as the position of the actuator is varied.
