Abstract

A novel design of the DBD actuator/sensor is proposed for mapping the location of the icing on a surface. The new design uses segmentation of the embedded electrode of the DBD actuator. Segmented DBD actuator/sensor devices were fabricated and experimentally tested in terms of mechanical, thermal and sensing abilities. The sensing capability of the new actuator was analyzed experimentally. Stationary and dynamic icing tests were conducted and the electrical characteristics of the DBD were measured. An optimization study on the effect of the electrode dimensions on the degree of sensitivity of the device was performed. Experimental results show that by using a segmented configuration it is possible to sense the onset of ice formation and also to detect its location. In addition, it is possible to detect the regions where the ice layer is thicker, the time it starts the melting process and the time that water/ice are expelled from the surface. In addition, it is shown that the segmented actuator has better deicing performance in comparison the conventional actuators. It is also shown that the thermal and active flow control abilities are not compromised by the segmented configuration and thus this device may perform deicing, ice formation and location detection and active flow control.
