| Abstract | The atmospheric plasma generated by electrohydrodynamic(EHD) plasma actuator could directly convert electric energy into kinetic energy of the surrounding air and propel the layer flow to accelerate as a result. Therefore, it enjoys a promising future in the area of flow control and has attracted much attention. However, most of current simulations and experiments focus on the horizontal component of the induced velocity, and are not capable of identifying the angle of the induced velocity vector. Considering any significant amount of vertical momentum would lift the flow off the surface and generate turbulence and vortices, a special plasma actuator test stand is desiged and the vertical thrust induced by plasma actuator is measured precisely on it, using both differential and direct methods. Besides, direct measurement of vertical velocity of induced flow is also carried out on the test stand. All the experiment results show that, vertical thrust and velocity induced by EHD plasma actuator is negligible or non-existent at all. |
