“…The maximum capacity of the electrical balance was 620 g, repeatability was 0.001 g, and linearity was 0.002 g. The time resolution of the measurement was approximately 0.4 s, and the time-averaged thrust was obtained. The thrust varies over time owing to the surface temperature change during the measurement [15], and this variation is included in the error bar as the uncertainty of the measurement.…”

“…Only 0.2% of the total electric power consumed by the DBDPA is used to generate mechanical power of induced flow [11], and most of the power consumed by the DBDPA was dissipated as heat [12]. It has been reported that heating the dielectric surface affects the mechanical and electrical characteristics of the DBDPA [13][14][15]. Shen et al showed that capacitance, power consumption, plasma brightness, and surface temperature increased with operation time [15].…”

“…It has been reported that heating the dielectric surface affects the mechanical and electrical characteristics of the DBDPA [13][14][15]. Shen et al showed that capacitance, power consumption, plasma brightness, and surface temperature increased with operation time [15]. Erfani et al clarified that the maximum velocity of the ionic wind was affected by the dielectric surface temperature in experiments that altered the actuator temperature using a Peltier heater and dry ice [14].…”

“…However, the discharge generates not only ionic wind, but also surface heating, which reduces the cooling effect. Thermal measurements in previous studies have reported that the surface temperature of the DBDPA could rise by several tens of Kelvins [13,15,[27][28][29][30]. Heat dissipation and surface heating are the severe problems associated with cooling systems.…”

Dielectric barrier discharge plasma actuators (DBDPAs) have been investigated for active flow control. The discharge induces ionic wind, which can be utilized for flow control; however, it simultaneously heats the flow and the dielectric surface. The thermal characteristics of the DBDPA must be clarified for applications in thermo-fluid engineering, such as forced convective cooling. In this study, we constructed a similarity law for the time variation of the surface temperature, assuming that the induced flow was heated by the discharge and that the dielectric was heated by the airflow. The similarity law was derived from the one-dimensional heat conduction equation in the dielectric, and the spatially averaged normalized temperature was then formulated as a function of the Biot and Fourier numbers. To experimentally validate the similarity law, the surface temperature, thrust, and power consumption were measured. The induced flow temperature and heat transfer coefficient were estimated based on the thrust and power consumption. The measured results verified that the similarity law was valid, regardless of the dielectric material, thickness, or applied voltage. This result supports the hypothesis regarding the heating mechanism in which the airflow is heated by Joule heating and the dielectric is heated by forced convection.

Dielectric Discharge Barrier (DBD) plasma actuators are considered as one of the best active electro-hydrodynamic control devices, and are considered by many contemporary researchers. Here a simple electrostatic model, which is improved by authors, and uses the Maxwell’s and the Navier–Stokes equations, is proposed for massive optimization computations. This model is used to find the optimum solution for application of a dielectric discharge barrier on a curved surface of a DU25 wind turbine blade airfoil, in a range of 5–18 kV applied voltages, and 0.5 to 13 kHz frequency range. Design variables are selected as the dielectric thickness and material, and thickness and length of the electrodes, and the applied voltage and frequency. The aerodynamic performance, i.e. the lift to drag ratio of the wind turbine blade section is considered as the cost function. A differential evolution optimization algorithm is applied and we have simultaneously found the optimized value of both geometrical and operational parameters. Finally the optimized value at each voltage and frequency are sought, and the optimum aerodynamic performance is derived. The physical effect of each design variable on the aerodynamic performance is discussed. A design relation is proposed to recommend an optimum design for wind turbine applications.
