“…We believe that both serpentine and multi-barrier plasma actuators have numerous aerodynamic applications where an increased mixing of the local fluid is desired. The areas of boundary layer transition, convective heat transfer, and plasma assisted combustion (PAC) 23 all contain flow fields in which an improvement in flow turbulization could significantly enhance the desired output. An experimental study using a serpentine actuator on a freestream boundary layer of such an application remains open for evaluation in the near future.…”

“…There has been significant research in this area for standard AC-DBD actuators at low speeds. [34][35][36][37][38][39][40][41] These studies have shown that 2D actuators create an out-of-plane velocity component that does not exist with 1D linear actuators. This out-of-plane velocity enhances mixing in the region which could prove useful for a number of applications e.g.…”

“…In our prior study [12][13], we presented the serpentine actuator induced flow mixing on a flat surface and a gas turbine combustor. The results showed three-dimensional plasma effects extract momentum from an upstream flow injecting it into the bulk fluid through localized pinching and spreading effects.…”

We numerically predict nanosecond pulsed dielectric barrier discharge (DBD) actuators for combustion stabilization. Three problems are considered in the present study. First problem is a benchmark case which is compared with reported experimental data. Numerical results show good agreement with velocity components in axial-, radial-and tangential-directions. For the comparison of flame temperature, we also show similar trend with the experiment. For the second problem, we employ serpentine plasma actuator for plasma assisted combustion. We numerically investigated the influence of inner and outer recirculation zones interacts with the serpentine plasma actuators. Also, the details of the flame shape and combustion stabilization mechanism are examined. The last problem is to use nanosecond pulsed plasma actuators for stabilizing the flame. The results show that the nanosecond pulsed actuators are able to stabilize the flame near the walls. This may also enhance combustion efficiency for a lean-burn condition.
