Resumen:
The drag reduction in a circular cylinder was explored by means of a novel three
electrode plasma actuator (DBDE). The DBDE actuator can reduce the drag coefficient up to a
~25% respect to the base flow drag coefficient. It has been demonstrated that, within the
present experimental conditions, the DBDE actuator, for a fixed value of the power coefficient,
adds a higher momentum to the flow and, consequently, produces a higher drag reduction than
the DBD actuator with the same power coefficient. The actuator efficiency was analysed in
terms of the momentum added to the flow revealing similar behaviour for both kind of
actuators. However to produce similar levels of actuation both kind of actuators require
different values of VAC voltages that resulted always lower for DBDE. The reduction in this
high voltage value is highly beneficial as is directly related to: a lower HV AC source power
requirement, a reduction in the dielectric breakdown probability of the device and a reduction
in leakage currents.
