The objective of this research is to demonstrate the advantage and characterize the thrust performance and the induced flow field generated by the TED plasma actuator with sawtooth electrode. The induced body force of the sawtooth TED plasma actuator was investigated on quiescent air, by measuring thrust of the induced jet. A time-resolved PIV was used to acquire velocity field. From the results of the thrust measurement, it was confirmed that the sawtooth TED actuator enhances the thrust compared to the straight-edge TED actuator. From the PIV analysis, it was clearly found that the sawtooth TED actuator generates uniform facing jet from both of the electrode, by the uniform generation of the plasma from the sawtooth vertexes.
