Abstract: Fluids in a dielectric barrier glow discharge at atmospheric pressure have attracted interest from communi-ties of thermo and Àuid d\namics as well as control. 7his worN investigated the effects of a plasma actuator operating at . N9 and .N+] on the pressure distribution around a pol\vin\l chloride circular c\linder in low-velocit\ airÀow. 7he e[periment was repeated with the actuator at various angles. 7he results show an acceleration of the Àow demonstrated b\ a lower pressure coef¿cient at the actuator area. 7he Àow separation was also dela\ed b\ an angle of as much as . 7hese effects were shown to be greater when the actuator was positioned at an angle closer to the separation area.
Keywords: *low discharge'ielectric barrier discharge Flow control3lasma actuator6\nthetic plasma Met.
