| الملخص: | The optimum operating conditions of dielectric barrier discharge (DBD) plasma actuators were
determined using both the quantitative and qualitative methods. The quantitative study was carried
out by estimating DBD discharge power using the theoretical and experimental methods. The
theoretical analysis was carried out to find a mathematical model, which describe the discharge
power of the DBD actuator. The estimated results from the mathematical model were compared
with the experimental values obtained from Lissajous figures. The qualitative analysis was used for
the plasma flow visualization. The effects of the DBD design parameters were studied through the
images captured using a high speed charge-coupled device camera. Simulation work was done in
order to obtain an insight of the electric field responsible for the plasma formation using the
commercial computer software. The results revealed that the performance of the DBD plasma
actuator was influenced by various design parameters, especially by dielectric thickness and
controlled by the input voltage characteristics. |
