Electrohydrodynamic flow control. Status report 2007

This status report describes the work performed on electrohydrodynamic flow control during the year 2007. Much effort has been devoted to the spreading of knowledge, both outside and within FOI with the purpose of creating an interest for the technology and to build a network. Practical work has been initiated through a series of experiments where electrode materials and geometries have been tested. These experiments have shown that the efficiency of the surface mounted plasma actuator is highly dependent on geometry. Especially the electrode geometry is of great importance to the electrical to mechanical efficiency of the actuator.
