Abstract

The drag of an axisymmetric body of revolution in a nominally gradientless incompressible flow under the action of eddy breakup devices (EBU) is studied experimentally. It is demonstrated that the use of EBUs in the boundary layer may reduce the net drag of the body of revolution approximately by 1.75%, as compared with the corresponding value for the original configuration. An increase in the chord length of single-element devices and the height of their location in the boundary layer is found to gradually reduce the EBU effectiveness and, hence, to increase the net drag, as compared with the original configuration.
