Abstract: Dielectric barrier discharge produces ionization effect, aerodynamic effect, and thermal effect, and therefore can be used for aircraft anti-icing and deicing. The air-gap on the rear electrode influences both the discharge times per cycle and the charge distribution for Surface Dielectric Barrier Discharge (SDBD) actuators with Alternating Current power supply (AC-SDBD), and frequency is also an important factor affecting temperature rise of the actuator. However, current research on the temperature rise effect of AC-SDBD is based on the configuration without air-gaps on the rear electrode, and lacks high excitation frequencies above 15 kHz.The contrast configurations with and without air-gaps on the rear electrode are built. In the high frequency range of 35-55 kHz, the temperature rise characteristics of AC-SDBD are studied using the electrical characteristics, infrared temperature measurement, and discharge morphology. The results show that the maximum temperature on the exposed surface of the AC-SDBD actuator with air-gap on the rear electrode is 151.51% as much as that without air-gap when the same voltage or frequency is applied. The existence of the air-gap on the rear electrode can enlarge the temperature rise area on the exposed surface of the actuator, particularly in the direction opposite to the discharge. The temperature increases nonlinearly with the rise of frequency, thereby reducing the risk of high voltage breakdown.
