Abstract:
Dielectric barrier discharge may produce the ionization effect, the aerodynamic effect and the thermal effect, which can be used as a new way of anti-icing for aircraft. The excitation frequency is one of main factors that affect temperature rise of alternating current dielectric barrier discharge (AC-DBD), however, the research results under high frequency are not widely available in the literature. Consequently, we performed the experiments of temperature rise for ionized gas and electrode of AC-DBD in the frequency range of 30~55 kHz. The results show that graphene coating is helpful to reducing the measurement error of metal electrode via infrared thermometry. The high temperature can be produced under the high frequency, and the temperature of ionized gas can reach 323.27 ℃ when the peak-peak voltage is 22 kV and the frequency is 50 kHz. The temperatures of ionized gas and electrode increase nonlinearly with the rise of voltage, and the temperature rise will quicken at higher voltages. The temperature will increase nonlinearly with the rise of frequency, and the temperature rise will quicken at higher frequency. This study supplies the certain reference for achieving the preferable anti-icing effect by DBD actuator.
