This study employs Detached Eddy Simulation (DES) to investigate the influence of Dielectric Barrier Discharge (DBD) plasma actuators on the control of non-reacting flow structures within a non-premixed bluff body burner. Plasma actuators were used in two operating modes of continues and duty-cycled actuation. The objective is to assess the efficacy of plasma actuators in manipulating flow characteristics for enhanced combustion control. The numerical simulations are conducted to elucidate the interaction between the plasma actuation and the turbulent flow around the bluff body burner by analyzing flow separation, vorticity dynamics, and overall flow structure. Our findings reveal that the plasma actuator significantly influences recirculation areas, demonstrating effectiveness in enhancing the mixing of fuel and oxidizer. The presence of the plasma actuator induces the formation of a vortex, slowing down flow movement and improving the interaction between fuel and airflow streams, thereby promoting more favorable combustion conditions. Results reveal significant modifications in the flow field, shedding light on the potential of DBD plasma actuators as active control devices in non-premixed combustion scenarios. The findings of this study provide valuable insights into the mechanisms underlying plasma-based flow control, paving the way for further exploration in reactive flow environments.
