The effects of voltage waveform characteristics and electrode dimensions on the flow induced by using a dielectric barrier discharge plasma actuator (DBD-PA) have been investigated in this study. It is known that the flow is induced in the direction from the upper electrode to the bottom electrode, then tangential one-way flow can be generated by using DBD-PA with asymmetric electrodes. We found, however, that it is possible to reverse the flow direction in certain conditions when offset voltages with a pulse wave are varied. Setting the negative offset, the flow is reversed by applying pulse wave in any electrode dimension. It should be noted that it is not reversed by sine waves even with same amplitudes and frequencies. Our experimental results indicate that the voltage surge velocity is important to realize reversed flow induced by DBD-PA.
