“…It is clearly seen that, at a high actuator's pulse repetition rate, practically no ice accretion on the surface occurs. In [244,245], the results of [242,243] were confirmed using the longitudinal arrangement of the electrodes of a nanosecond actuator, similar to that used in [212] to control the boundary layer separation in transonic regimes (Fig. 74).…”

Abstract— The paper presents a review of modern works on gasdynamic flow control using a highly nonequilibrium pulsed plasma. The main attention is paid to the effects based on ultrafast (on the nanosecond time scale for atmospheric pressure) local gas heating, since, at present, the main successes in controlling high-speed flows by means of gas discharges are associated with this thermal mechanism. Attention is paid to the physical mechanisms responsible for the interaction of the discharge with gas flows. The first part of the review outlines the most popular approaches for pulsed energy deposition in plasma aerodynamics: nanosecond surface barrier discharges, pulsed spark discharges, and femto- and nanosecond optical discharges. The mechanisms of ultrafast heating of air at high electric fields realized in these discharges, as well as during the decay of the discharge plasma, are analyzed separately. The second part of the review gives numerous examples of plasma-assisted control of gasdynamic flows. It considers control of the configuration of shock waves in front of a supersonic object, control of its trajectory, control of quasi-stationary separated flows and layers, control of a laminar–turbulent transition, and control of static and dynamic separation of the boundary layer at high angles of attack, as well as issues of the operation of plasma actuators in different weather conditions and the use of plasma for the de-icing of a flying object.

The icing events for the wind turbine blade is the key problem in the low temperature conditions. Heating is considered to be the most efficient approach to prevent from the ice formation on the turbine blade surface. However, this kind of method consumes a certain amount of energy. In this present study, an anti-icing method, using the heat pipe technology, is proposed to prevent from icing on the blade surface, and the anti-icing energy is from the waste heat generated during the operation of a wind turbine, which can reduce the assumption of the energy. The researches on the anti-icing temperature characteristics of the test model, based on the heat pipe anti-icing method, are carried out in an icing wind tunnel combining with the low natural temperature. The effects of the wind speed and heat source temperature on the heat transfer of heat pipes are investigated. The icing distribution and the temperature change of the anti-icing process of an airfoil with NACA0018 are explored, and the variation of the icing thickness of the airfoil with icing time, under the different heat source temperature conditions, is analyzed. The results indicate that the blade surface temperature, which is lower than 0?C, is more beneficial to the heat transfer of the heat pipe, and the ice prevention, based on the heat transfer of the heat pipe, can achieve a better anti-icing effect.

“…The working principle of the heat knife is to ''cut'' the ice into blocks, 18 and aerodynamic force can sweep the ice from the surface as soon as the adhesion force at the ice-surface interface is removed by periodic heating. 19,20 Though electro-thermal de-icing system has many advantages, its power requirements need to be minimized, 21 because there is a growing demand for new technologies that will enable aircraft operators to burn less fuel. 22 Since the heat knife works continuously and usually covers the entire span of a protected wing, its energy consumption is almost half that of the entire electro-thermal de-icing system.…”

Traditional electro-thermal de-icing strategy has the drawback of high energy consumption and its heat knife accounts for a considerable amount of the cost. Compared to electro-thermal de-icing, thermo-mechanical expulsion de-icing system eliminates the heat knife by combining electric-heating with electro-magnetic expulsion de-icing system. The consumption is significantly lower but the system has complex mechanical structures. In this article, a novel de-icing strategy combining electric-heating with plasma synthetic jet actuator is proposed for the first time. Its main idea is to replace heat knife with a simple mechanical device. During the de-icing process, the electric-heating is used to remove the adhesion force, then a single pulse of plasma synthetic jet actuator exerts a rapid force on ice and makes it fracture. Schlieren imaging shows plasma synthetic jet actuator can make free ice columns fracture into pieces and powder. The ice can even be completely penetrated by pressurized air when the discharge energy is relatively large. And compared with the non-deicing process, the intensities of waves and jets are significantly weakened. During the hybrid de-icing process, high-speed photography shows that plasma synthetic jet actuator can divide an ice layer 200 mm in diameter and 10 mm in thickness into multiple blocks completely in tens of milliseconds after electric-heating removes the adhesion force. Besides, energy consumption of plasma synthetic jet actuator in a de-icing cycle accounts for only 0.27% of the whole system. Compared with the free ice columns of the same size, the ice debonded by electric-heating fragmented into smaller blocks after activating plasma synthetic jet actuator. However, heating for too long does not bring more beneficial effects on the fracture of ice in this experiment. At last, a new “micro piston ice-breaker” which is waterproof is proposed to meet the needs of in-flight de-icing.
