Abstract :
A new actuator configuration has been developed that aims to mitigate high viscous losses due to the local momentum injection near a bounding surface and to demonstrate improvement thereof in electro-fluid mechanical efficiencies. This development builds on the success of a dielectric barrier discharge driven plasma channel by exploring an electrode configuration that directly actuates the bulk fluid minimizing jet impingement and viscosity related losses of a traditional surface plasma actuator. Influence of several electrical and physical parameters including electrode materials are experimentally investigated. Results indicate that in comparison to surface dielectric barrier plasma actuator, at least an order of magnitude improvement in energy conversion efficiency is possible. The jet produced from this plasma channel configuration allows greater versatility for applications in boundary layer flow control and internal flows.
