The experiment revealed the effect of the enable voltage characteristics on the flow induced by the plasma actuators. Conventionally, the flow was induced only in the direction from the upper electrode to the bottom electrode in general conditions, but it was enable to reverse the flow direction in certain conditions. We controlled the flow by offset voltage. We have experiment under those conditions; normal type, positive-offset type, and negative-offset type. Using the positive-offset, the flow was stronger than normal type. Using the negative-offset, the flow was induced in the direction from the bottom electrode to the upper electrode. The direction of the flow was reverse in the condition of negative offset. Not only the flow velocity but also the flow direction can be controlled by controlling the supplied voltage.
