Abstract A dielectric barrier discharge plasma actuator was used to control a jet flame produced using a gas mixture of 16−55 % propane volume concentration in air from a round convergent nozzle with a diameter of 6 mm. The electrode structure consisted of a dielectric body and a pair of coaxial copper electrodes. The applied voltage was 5−8 kV at a frequency of 6 and 8 kHz. The stability limit and flame shape were investigated with and without plasma generation using a high-speed camera. The results indicated that a longer flame could be maintained in the presence of plasma, and that the stability of the flame increased with applied voltage. This is thought to be due to the generation of an induced flow and active species by the plasma.
